Glasses for Heart-Shaped Face: Size Chart With Real Frame Measurements

If your forehead is the widest part of your face and your chin narrows to a point, reach for oval, round, or rimless frames. Below is a side-by-side size chart of frames that suit a heart-shaped face, pulled directly from brand product pages.

Short answer first

A heart-shaped face is widest at the forehead, with high cheekbones and a narrow, pointed chin. To rebalance it, choose oval, round, or rimless frames — or any frame that carries more visual weight along the bottom rim — and keep the top of the frame light. Aim for a total frame width slightly wider than your forehead. Avoid oversized frames and heavy, dark brow lines, which pile weight onto the widest part of your face. Before you buy, check the three measurements on every frame product page: lens width, bridge width, and temple length. Not sure you have a heart-shaped face? Use the face shape detector to check your four image measurements.

How to Read the Three Numbers

Every pair of glasses has three key measurements printed or listed. Here is what each one means for a heart-shaped face:

Unit Conversion: Millimetres to Inches

Some brands list sizes in millimetres; others show inches. If you need to convert, use 1 inch = 25.4 millimetres. Below are worked examples using actual rows from the table above.

Example 1 — Zenni #127339 (lens width)

Convert 52 mm to inches:

52 ÷ 25.4 = 2.0472 in
→ 2.05 in (rounded to two decimals)

So the Zenni #127339 lens width of 52 mm is roughly 2.05 inches.

Example 2 — Yesglasses Lachard e19304 (bridge width)

Convert 23 mm to inches:

23 ÷ 25.4 = 0.9055 in
→ 0.91 in (rounded to two decimals)

So the Yesglasses Lachard bridge width of 23 mm is roughly 0.91 inches.

Example 3 — Yesglasses Lachard e19304 (temple length)

Convert 150 mm to inches:

150 ÷ 25.4 = 5.9055 in
→ 5.91 in (rounded to two decimals)

So the Yesglasses Lachard temple length of 150 mm is roughly 5.91 inches.

Going the other way — inches to millimetres — multiply by 25.4 instead of dividing.

What the Size Numbers Cannot Tell You

Shape direction and the right millimetres are a useful starting point for a heart-shaped face. They do not guarantee comfort. Three things the three-number size does not capture:

  1. Nose pads and bridge fit. A heart-shaped face narrows below the cheekbones, so more of the frame's weight rides on your nose. Adjustable nose pads let you spread that weight and set the height; a fixed saddle bridge is lighter but hard to reposition if your nose does not match its moulded shape.
  2. Temple pressure and grip. Temple length tells you how long the arm is, not how it curves behind your ear. On a tapered lower face the ears often sit slightly further back, so a frame with the right length can still slide forward if the temples bow outward, or press if they bow inward. Spring hinges help but do not replace a try-on.
  3. Lens weight once glazed. A frame that balances nicely with demo lenses can tilt forward once your prescription is cut in. Higher prescriptions mean thicker, heavier lenses, and on a heart-shaped face the narrow chin gives the frame less support at the bottom — front-heavy frames are the ones that end up sliding.

Honesty note. This page gives you size numbers and shape direction for heart-shaped faces. It is not a fitting guide and it cannot tell you whether a specific frame will feel good on your face. The only way to know is to put the frame on, wear it for at least ten minutes, and check for sliding, pressure marks, and comfort when you look down.
