The goal when fitting a heart-shaped face is specific: add visual weight to the lower face while minimizing the apparent width of the forehead. Heart-shaped faces are widest at the brow line, with high cheekbones that taper progressively to a narrow chin. The frames that work best shift visual attention downward and outward from the chin, rather than compounding the weight already present in the upper face. Frames that fail this test (top-heavy designs, heavy embellishments along the brow bar, wide rectangular upper sections) leave clients looking more top-heavy than when they walked in.
For clients with this shape, the dispensing principle is bottom-up weighting rather than the angular contrast used for round or square faces. The practical implications are covered in the sections below.
How to Identify a Heart-Shaped Face: 4 Measurements That Confirm the Shape
A heart-shaped face is defined by a specific width hierarchy: the forehead is the widest horizontal measurement, the cheekbones are slightly narrower or equal, and the jaw and chin are considerably narrower than both. According to Optometrists.org, a heart-shaped face is one where “the widest part of your face is at your brow line, your cheekbones are high, and your face narrows down to your chin.”
Take four measurements to confirm the shape:
Step 1: Measure Forehead Width
Measure horizontally at the widest point of the forehead, typically at the temples, just below the hairline. This is almost always the widest measurement on a heart-shaped face.
Step 2: Measure Cheekbone Width
Measure from the most prominent point of one cheekbone to the other, passing across the nasal bridge. In a heart shape, this reading is close to the forehead measurement but slightly narrower.
Step 3: Measure Jaw Width
Measure at the angle of the mandible, from one side to the other, below the ears. This reading should be significantly narrower than the forehead measurement.
Step 4: Measure Face Length
Measure from the center of the hairline to the tip of the chin. In a pure heart shape, the face length is typically greater than the forehead width, giving the shape a vertical emphasis that is easy to misread as an oval.
Interpreting the Results
| Measurement Pattern | Indicated Shape |
|---|---|
| Forehead widest, jaw and chin narrow, taper gradual | Heart shape |
| Forehead widest, chin very pointed, sharp taper | Inverted triangle |
| Cheekbones widest, forehead and jaw narrower | Diamond shape |
| All horizontal measurements similar, face height equal or less | Square or round |
| All measurements similar, face notably longer than wide | Oval |
The heart shape can be confused with the diamond shape during consultation. The key difference is at the forehead: a diamond face has a narrow forehead that is significantly less wide than its cheekbones, while the heart face has a forehead that is the widest point of the entire face. If the client’s forehead is the broadest horizontal measurement, the shape is heart, not diamond.

Why the Heart Shape Creates a Specific Fitting Problem
The challenge with heart-shaped faces is optical imbalance rather than structural complexity. A wide forehead paired with a narrow chin creates a strong top-heavy visual impression. Any frame that draws additional attention to the upper face intensifies this imbalance. Any frame that draws attention downward or widens the perceived chin area corrects it.
This is a different problem than fitting a square face, where the goal is to introduce curved contrast against angular features. With a heart-shaped face, the dominant issue is distributing perceived width more evenly across the vertical axis of the face. Frames need to act as a counterweight to the forehead, not as an accent of it.
The dispensing principle: frames should appear to add width near the cheeks and chin, and they should avoid creating a heavy visual bar across the upper face.
A quotable framing from Optometrists.org makes this practical: “Balance a narrow chin by creating more width with a bottom-heavy frame. Draw attention away from your forehead with low-set temples that will help to emphasize the lower part of your face.”
This principle applies to every frame recommendation below.
Best Frame Styles for Heart-Shaped Faces
Aviator and D-Frame Styles
Aviators are the strongest default recommendation for heart-shaped faces. The teardrop or D-frame shape is wider at the bottom of the lens than at the top, which is the geometric opposite of the face’s proportions. As West Broward Eyecare notes, “Aviators are a great example of this; they get wider at the bottom of the spectacle,” making them a natural fit for adding visual weight precisely where the face narrows.
Optometrists.org specifically names “winged-out frames that protrude out and away from your forehead, such as an aviator or D-frame shape” as the most complementary styles for heart-shaped faces.
For dispensing purposes, select aviator frames where:
- The bottom rim is the widest point of the lens, not the top
- Temple attachment sits low on the lens, rather than at or above the midpoint
- Bridge width is narrow enough to sit flush at the nose without creating forehead-level visual emphasis
- Frame material is lightweight metal or titanium, which avoids adding bulk at the upper face
Bottom-Heavy Frames
Any frame style where the lower rim is thicker, darker, or more detailed than the upper rim qualifies as bottom-heavy. The lower visual weight draws the viewer’s gaze down toward the chin area, partially compensating for the face’s narrow lower portion. West Broward Eyecare describes this class of frames precisely: “Eyeglass frames with extra detail or weight on the bottom draw the eye downward, perfect for adding visual weight to the lower half of your face.”
A semi-rimless frame with the rim running only along the bottom edge of the lens is the most extreme version of this effect and suits clients who prefer a minimal appearance with maximum downward emphasis. All About Vision notes that “rimless and semi-rimless eyeglasses are minimalist frames that draw attention away from your stronger facial features and keep your look light” for heart-shaped faces.
Oval Frames
Oval frames are a reliable, versatile choice. They have no sharp angles to add upper-face emphasis, and their horizontal width gives the chin area more visual presence without requiring a dramatic bottom-heavy design. All About Vision recommends oval glasses specifically for heart-shaped faces, noting they “help soften and balance out any angles.”
Ovals suit a wide range of prescriptions and face sizes, making them a safe recommendation when the client is undecided between styles or when high-index lenses create edge-thickness concerns that rule out narrower frames.
Rectangular Frames (Conditions Apply)
Thin rectangular frames in light colors or metal can work for heart-shaped faces, provided the rectangle is horizontal (wider than tall) and the frame does not have a heavy or decorated upper bar. All About Vision describes this well: “Rectangular glasses balance out the curves of your heart-shaped face. A pair of thin metal frames in a light color will keep your features from looking too top-heavy.”
The key qualifier is frame weight and decorative emphasis. A thin, clean-lined metal rectangle distributes attention evenly. A thick acetate rectangle with a prominent brow bar shifts attention upward and should be avoided.
Light or Translucent Frame Colors
Frame color interacts with perceived facial width. Lighter frame colors (gold, clear acetate, blush, translucent materials) reduce the visual weight across the upper face. Darker, opaque frames read as heavier and can intensify the top-heavy impression. For heart-shaped faces, light frames are not merely aesthetic preference; they serve a functional fitting purpose. Poudre Valley Eye Care confirms that “glasses in light colors with minimal frames will set off your features beautifully” for this face shape.
Frame-to-Face Measurement Ratios for Heart-Shaped Clients
Proportional fit requires more than style selection. The following measurement targets are specific to the heart-shaped face geometry.
Frame Width Relative to Forehead Width
The West Broward Eyecare frame selection guide states the goal clearly: “Frame edges should fall between your cheekbones and face sides.” For a heart-shaped face, the practical target is for the outer edges of the frame to align with or extend slightly beyond the widest point of the forehead, not the cheekbones.
This is the opposite of the fitting instruction for round or oval faces, where the frame is matched to cheekbone width. On a heart-shaped face, matching the frame to cheekbone width produces a frame that is narrower than the forehead, which makes the forehead appear even wider by contrast.
Target: total frame width within 2-4 mm of measured forehead width, allowing the frame to sit visually level with the brow without creating overhang.
Bridge Width and Nasal Fit
Bridge size is particularly important for heart-shaped clients because the bridge position determines where the frame sits vertically on the face. West Broward Eyecare specifies that “the bridge size (14mm-19mm range) cannot be adjusted on plastic frames, so exact measurement is essential.”
For heart-shaped clients, a narrower bridge (14-16mm) positions the frame higher on the face and draws the eye toward the upper nasal area, which can add vertical emphasis without widening the forehead. A wider bridge (18-20mm) drops the frame slightly, shifting emphasis toward the mid-face. Either can work depending on the client’s nose bridge anatomy, but the fitting must be measured and confirmed rather than estimated.
Low-set temples (temple attachment at or below the optical midpoint of the lens) reinforce the downward visual emphasis that benefits this face shape.
Frame Width Reference by Face Size
| Face Width at Forehead | Target Total Frame Width |
|---|---|
| 120-128 mm (narrow) | 118-130 mm |
| 128-136 mm (medium) | 126-138 mm |
| 136-145 mm (wide) | 134-147 mm |
These ranges allow for slight overhang at the temples, which is appropriate here. Frames that are narrower than the forehead should not be selected for heart-shaped clients.
Pupillary Distance and Optical Centering
Any significant frame width change requires PD re-verification. According to a clinical review published in PMC, “if the pupillary distance is measured incorrectly, the optical centre will be incorrectly set within the spectacle frames, which can only be rectified by remeasuring the pupillary distance correctly, and remaking the spectacles.”
The same source notes that “if the frame is too big or too small, or if it has been poorly adjusted, this can lead to misalignment of the optical centre, even when the pupillary distance has been measured correctly.” For heart-shaped clients selecting a wider-than-forehead frame, this risk is real and requires a fresh PD measurement with the frame in place.
For context on how face geometry relates to PD distributions across real-world patient populations, the Optogrid PD measurement study draws on 14,904 measurement sessions to document how facial proportions, including asymmetry, vary across clients.
For clients using progressive lenses, frame lens height needs separate verification. See the round face fitting guide for progressive lens height benchmarks, which apply across all face shapes.
The Cat-Eye Question: Why Popular Consumer Advice Oversimplifies
Consumer eyewear publications consistently list cat-eye frames as a top recommendation for heart-shaped faces. The rationale is that the upswept outer corners draw attention to the cheekbones and create a “lifting” effect. West Broward Eyecare describes this as: “the upswept corners draw attention to your cheekbones and give a little lift to your face.”
The problem is that this advice omits a critical constraint. Cat-eye frames are designed to be widest and most visually prominent at the upper outer corner of the lens. On a heart-shaped face, where the forehead is already the dominant width feature, a strong cat-eye with high, flared temples compounds the top-heavy proportion rather than correcting it. The upsweep adds visual mass precisely where the face already has the most, and draws attention away from the chin rather than toward it.
This matters for dispensing because clients frequently request cat-eye frames based on consumer style guides, and pushing back without a clear explanation creates friction.
The clinical rationale: the cat-eye recommendation is valid only for frames with a modest, low-set sweep where the frame’s widest point falls at or below the pupil center, not above it. A steep cat-eye with a prominent brow bar and high outer corners functions as a top-heavy frame and should be categorized accordingly. West Broward Eyecare confirms the risk: “Super heavy or overly embellished eyewear at the top can make your forehead appear even wider.”
The practical dispensing instruction: if a client requests cat-eye frames, guide toward styles where the upsweep is subtle, the frame material is lightweight or translucent, and the outer temple attachment point is at or below the optical center of the lens. Avoid bold, high-arching cat-eyes with thick upper bars.
Frames to Avoid for Heart-Shaped Faces
| Frame Type | Why It Fails |
|---|---|
| Heavy upper-bar browline (clubmaster) | Adds visual weight across the brow; compounds forehead width |
| Bold cat-eye with steep upper sweep | Draws attention to the widest part of the face |
| Top-heavy acetate with thick upper rim | Increases perceived forehead mass |
| Narrow rectangular frames (portrait orientation) | Neither widens chin nor reduces forehead; provides no balance |
| Decorative upper-temple embellishments | Adds visual interest at the forehead; accentuates width |
| Oversized round frames | Too wide; floats around the face without providing directional balance |
As West Broward Eyecare states plainly: “Avoid square and rectangular frames that add sharp angles and emphasize a wide forehead.”

Heart-Shaped Face Fitting Checklist (Dispensing Table Reference)
A practical 7-item checklist for opticians fitting a client with a confirmed heart-shaped face:
- Measure and record forehead width at the temples (this is the critical reference measurement for frame width selection)
- Select frame width at or slightly beyond forehead width (within 2-4 mm), not matched to cheekbone width
- Confirm low temple attachment: temple arms should connect at or below the lens midpoint, not at the top edge
- Check upper rim weight: reject frames with thick, embellished, or heavy upper bars; approve lightweight upper sections
- Measure bridge width against the client’s nasal anatomy; confirm the frame sits neither too high nor too low (bridge size cannot be adjusted post-purchase on plastic frames)
- Re-measure PD against the selected frame’s optical center, especially if the client is switching from a significantly narrower or narrower previous frame
- Verify lens height for progressive compatibility before finalizing the frame selection (minimum 28-30mm for most progressive designs)
For cases where the client is being fit remotely or through an omnichannel workflow, Optogrid’s photo-based measurement tool captures PD and segment height from a patient photograph taken with the selected frame in place, allowing optical centering to be verified before the order is submitted to the lab.
Heart Shape vs. Oval: How to Differentiate During Consultation
These two shapes are frequently confused because both have a narrower chin than forehead. The practical differences:
| Feature | Heart Shape | Oval Shape |
|---|---|---|
| Forehead vs. cheekbone width | Forehead noticeably wider | Cheekbones slightly wider than forehead |
| Jawline taper | Pronounced, leading to narrow or pointed chin | Gentle taper, rounded chin |
| Chin definition | Narrow or pointed | Soft and rounded |
| Best frame styles | Bottom-heavy, aviator, light oval | Most styles; angular frames add structure |
| What to avoid | Top-heavy, wide browline | Oversized frames; very small frames |
The key diagnostic question: “Is the forehead the single widest point?” If yes, the shape is heart. If the cheekbones are as wide or wider, the shape is oval (or possibly diamond).

Frequently Asked Questions
What are the best glasses frames for a heart-shaped face?
Aviator and D-frame styles are the strongest default recommendation because their wider bottom section adds visual weight precisely where a heart-shaped face is narrowest. Bottom-heavy frames with detail or thicker rims along the lower edge, oval frames, and thin rectangular metal frames in light colors also work well. The unifying principle: frames should shift visual attention downward toward the chin and away from the forehead.
Why are top-heavy frames a problem for heart-shaped faces?
A heart-shaped face is already widest at the forehead and brow line. Frames with heavy upper bars, bold brow accents, or dramatic upswept corners add visual mass to the area that already dominates the face, intensifying the top-heavy proportion rather than correcting it. According to West Broward Eyecare, “super heavy or overly embellished eyewear at the top can make your forehead appear even wider.”
Do cat-eye frames work for heart-shaped faces?
It depends on the specific cat-eye design. Subtle, low-set styles where the outer sweep is modest and the frame material is lightweight can work. Bold cat-eyes with a steep upper sweep, wide flared temples, or a thick upper bar function as top-heavy frames and should be avoided for heart-shaped clients. If a client requests cat-eye frames, guide toward styles where the frame’s widest point falls at or below the pupil center.
How wide should frames be for a heart-shaped face?
Total frame width should align with or extend slightly beyond the measured forehead width, the widest point of the face. For heart-shaped clients, matching frame width to the cheekbones (the typical fitting rule for other shapes) produces a frame that is narrower than the forehead and makes the top-heavy impression worse. Aim for frame width within 2-4 mm of the measured forehead width.
What is the difference between a heart-shaped face and an oval face?
The clearest differentiator is where maximum width occurs. In a heart-shaped face, the forehead is measurably the widest point. In an oval face, the cheekbones are the widest horizontal measurement, with a gentle taper toward a rounded chin. Heart-shaped faces also tend to have a more pronounced chin taper, often ending in a narrower or slightly pointed chin, compared to the rounded chin typical of an oval shape.
Should the PD be re-measured when switching frames for a heart-shaped client?
Yes. Switching to a frame with a different width changes the optical center placement relative to the pupil. According to a clinical review published in PMC, if the pupillary distance is measured incorrectly “the optical centre will be incorrectly set within the spectacle frames, which can only be rectified by remeasuring the pupillary distance correctly, and remaking the spectacles.” A fresh PD measurement should be taken with the new frame in place.
Can rimless frames work for a heart-shaped face?
Yes. Rimless and semi-rimless frames are well-suited for heart-shaped clients who prefer a lighter, less prominent look. Without a visible upper rim, there is no top-heavy visual bar across the forehead. Semi-rimless designs with the rim running along the bottom of the lens are particularly effective because the single lower rim reinforces downward visual emphasis.
