Quick Reference: Frames by Face Shape

| Heart | Bottom-heavy frames, Oval, Light rimless | Cat-eye and top-heavy frames |
| Diamond | Cat-eye, Oval, Rimless | Narrow frames |

Glasses Recommendations by Face Shape
Detailed guidance for every face shape — frames to try, frames to avoid, and sunglasses picks.
Oval Face
View shape guide →Forehead slightly wider than jaw, gently tapered chin, balanced length-to-width ratio
Best Frames
- ✓Rectangle
- ✓Square
- ✓Geometric
- ✓Aviator
- ✓Browline
- ✓Oversized
Avoid
Very large frames that overwhelm the face proportions
Sunglasses Pick
Wayfarers, aviators, and cat-eyes all look excellent.
Why it works: Oval faces are considered the most versatile — virtually any frame works. Focus on keeping frame width equal to the widest part of the face.
Round Face
View shape guide →Face width and length roughly equal, soft curved jawline, full cheeks
Best Frames
- ✓Rectangle
- ✓Square
- ✓Geometric
- ✓Angular browline
- ✓D-frame
Avoid
Circular, oval, or round frames — they mirror the face shape and add more roundness
Sunglasses Pick
Wayfarer and angular shield frames add structure. Avoid round John-Lennon styles.
Why it works: Angular and wider-than-tall frames create the illusion of length and definition, counteracting the softness of a round face.
Square Face
View shape guide →Forehead, cheekbones, and jaw similar in width; strong angular jawline
Best Frames
- ✓Round
- ✓Oval
- ✓Cat-eye
- ✓Rimless
- ✓Semi-rimless
Avoid
Boxy rectangles and hard geometric frames that echo strong jaw angles
Sunglasses Pick
Round or hexagonal sunglasses (think Lennon or clubmaster) work beautifully.
Why it works: Curved frames soften the pronounced angles of a square jaw and add balance between face width and length.
Heart Face
View shape guide →Wide forehead, high cheekbones, narrow pointed chin
Best Frames
- ✓Bottom-heavy frames
- ✓Oval
- ✓Light rimless
- ✓Aviator
- ✓Low-set browline
Avoid
Cat-eye and top-heavy frames that add more width to the already wide forehead
Sunglasses Pick
Rounded aviators and oval shields are ideal. Skip oversized square frames.
Why it works: Bottom-heavy or light frames balance the wider top half with the narrow chin, creating a more proportionate look.
Diamond Face
View shape guide →Narrow forehead and chin, wide prominent cheekbones
Best Frames
- ✓Cat-eye
- ✓Oval
- ✓Rimless
- ✓Semi-rimless browline
Avoid
Narrow frames that emphasise wide cheekbones; overly geometric frames
Sunglasses Pick
Cat-eye and oval sunglasses complement diamond faces perfectly.
Why it works: Cat-eye and browline frames draw attention upward and add width to the forehead, balancing the wide cheekbones.
Oblong Face
View shape guide →Face noticeably longer than it is wide, narrow forehead and jaw, long straight cheek lines
Best Frames
- ✓Oversized square
- ✓Round
- ✓Wraparound
- ✓Deep lenses
- ✓Wide browline
Avoid
Small frames or narrow rectangular frames that lengthen the face further
Sunglasses Pick
Oversized round or shield sunglasses work well — the wider the better.
Why it works: Wide, deep frames add horizontal width and visual width to break up the length of an oblong face.
Triangle Face
View shape guide →Narrow forehead, wide jaw — sometimes called pear-shaped
Best Frames
- ✓Cat-eye
- ✓Semi-rimless top
- ✓Browline
- ✓Angular top-heavy frames
Avoid
Bottom-heavy frames that add width to an already wide jaw area
Sunglasses Pick
Aviators with a strong brow bar and cat-eye sunglasses are ideal.
Why it works: Top-heavy frames add visual width at the forehead to balance a wider jaw. Cat-eye shapes are especially effective.
Frame Types Explained
The style of frame — not just the shape — affects how it looks on your face. Here's what each type does:
Full-rim
Classic and bold. Makes a statement and defines the frame shape clearly. Best for strong prescriptions as the rim hides thick lenses.
Semi-rimless
Rim only along the top. Lighter look with a hint of structure. Good for softer face shapes that need subtle definition.
Rimless
Nearly invisible on the face. Ideal for oblong or long faces where you want width without visual weight.
Cat-eye
Upswept outer corners. Adds lift and femininity. Best for square, round, triangle, and diamond faces.
Browline
Thicker frame across the top with thinner or rimless bottom. Classic, intellectual look. Works for oval, round, and triangle faces.
Aviator
Teardrop shape with double bridge. Iconic and versatile. Works for oval, heart, and oblong faces.
Wraparound
Curved lenses that wrap around the face. Sporty look. Best for oblong and oval faces with a wider frame width.
Glasses for Men by Face Shape
The same face-shape geometry applies to men's frames, but men's eyewear typically features heavier frames, thicker temples, and a wider bridge. Here are the key picks:
Oval face — men
Wayfarers, aviators, and rectangles all work. Stick with frame widths that match the widest part of the face (usually cheekbones).
Round face — men
Bold rectangular or square frames (think thick plastic Wayfarers or navigator shapes) add definition and visual length. Avoid circle frames.
Square face — men
Round or oval frames soften the jawline. Clubmaster / browline styles are a classic choice — they add refinement without fighting the strong jaw.
Oblong face — men
Oversized or deep frames add width. Wraparounds and shield styles for sunglasses are a natural fit.
Heart face — men
Low-set browline frames, semi-rimless, and aviators balance a wide forehead against a narrower jaw. Skip top-heavy or cat-eye styles.

5 Frame Fitting Principles That Override All Rules
Face shape is a starting point — these practical rules matter just as much:
- 1Frame width should match your face width.
The frame edges should align roughly with the widest part of your face. Too narrow looks squeezed; too wide looks oversized.
- 2Eyebrows should be visible above the frame.
Brows frame the face — hiding them under the frame top edge disrupts natural facial expression and reads as dated.
- 3Pupillary distance (PD) must be correct.
Optically incorrect PD causes eye strain even with perfect face-shape framing. Get it measured before ordering online.
- 4Bridge fit is more important than style.
Glasses that slide down constantly look bad regardless of shape. Match the bridge width to your nose bridge for comfort and positioning.
- 5Skin tone affects colour — face shape affects shape, not colour.
Warm skin tones suit tortoiseshell, gold, and brown frames. Cool skin tones suit silver, black, and jewel tones. This is independent of face shape.

Frequently Asked Questions
- What glasses frames suit a round face?
- Angular frames — rectangles, squares, and geometric shapes — elongate a round face and add definition. Avoid circular or oval frames that echo the face's roundness.
- What glasses frames suit a square face?
- Round, oval, and cat-eye frames soften the strong angles of a square face. Avoid boxy rectangular frames that amplify the squareness.
- What glasses look best on an oval face?
- Almost any style works. Maintain the natural balance by keeping frame width aligned with the widest part of the face — typically the cheekbones.
- How do I find my face shape for glasses?
- Upload a photo to our free face shape detector for an instant AI result. Alternatively, measure your forehead, cheekbones, jawline, and face length with a tape measure.
- Do the same frame rules apply to sunglasses and prescription glasses?
- Yes — the same face-shape geometry applies to both. Sunglasses allow slightly bolder, oversized silhouettes since they function as statement accessories.
