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.
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.

Source notes: All seven rows — measurements from brand official US product pages (zennioptical.com, yesglasses.com, firmoo.com). Zenni rows: all three measurements visible in the Frame Size section of the product page. Yesglasses rows: lens width, bridge width, and temple arm length visible by default in the Dimensions section; the sidebar additionally shows "Size 48-23-150" for the Lachard and "Size 48-18-135" for the Belly. Firmoo rows: "Size: 51-18-147" for the TM39028 and "Size: 50-24-145" for the AC09219 visible in the Specifications section; both product pages show "in stock".

The same size chart is available as a CSV file so you can sort it, compare it against a frame you already own, or take it shopping.
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:
- Lens width — the horizontal width of one lens. On a heart-shaped face the forehead already leads, so a lens width between 48 and 54 mm keeps the frame proportional to the widest part of your face without crowding the narrower lower third. Oval and round lenses add curve where the face tapers, and short lens heights stop the frame from covering your cheekbones.
- Bridge width — the distance between the two lenses. This page spans 16 to 24 mm because the right bridge depends on your nose, not your face shape. A narrower bridge (16–18 mm) suits a slim nose; a wider one (22–24 mm) spreads the weight on a broader nose and keeps the frame from sliding down.
- Temple length — the length of the arm from hinge to ear bend. Most adult frames fall between 135 and 150 mm. This number decides whether the arm reaches your ear, not whether the shape balances your forehead — pick it last.

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:
→ 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:
→ 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:
→ 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:
- 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.
- 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.
- 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.
