If you already know your result from the face shape analyzer, here's a single reference page pulling together frame guidance for all seven shapes it detects, so you don't have to click through each dedicated guide individually.

| Shape | Frames that work well | Frames to avoid |
|---|---|---|
| Oval | Most shapes — rectangular, round, cat-eye, aviator | Oversized frames relative to face size |
| Round | Angular, rectangular; wider than tall | Round/circular frames |
| Square | Round, oval, rimless, thin frames | Heavy rectangular/square frames |
| Heart | Bottom-heavy cat-eye, rimless or light upper frames | Heavy browline/clubmaster styles |
| Triangle | Cat-eye, browline, bold upper-rim detail | Bottom-heavy or narrow frames |
| Diamond | Oval, rimless, brow or lower-rim detail | Frames exactly at cheekbone width |
| Oblong | Deeper lenses, browline/contrast across the top | Small, narrow frames |
Nearly every frame recommendation above follows one idea: a frame shape that contrasts with your face's dominant line tends to balance it, while a frame that echoes it tends to emphasize it. Angular faces (square) generally pair with curved frames; curved faces (round) generally pair with angular frames; faces with a width imbalance (heart, triangle, diamond) generally pair with frames that add width where the face is narrowest. Oval, lacking a single dominant feature to correct for, has the most flexibility.
These are widely-cited style heuristics, not strict rules — and which shape you actually are matters for applying them correctly. If you haven't run a photo yet, the analyzer gives you a specific, repeatable starting point (plus the exact ratio numbers behind it) in under a minute, entirely on your own device with nothing uploaded.
Frame shape is only one factor — frame size relative to your face, lens-to-eyebrow spacing, color, and material all affect how a pair of glasses looks on a specific face, in ways a shape category alone can't capture. Treat this page as a starting filter for browsing, not a definitive final answer, and don't hesitate to try on styles outside your "recommended" list — individual faces vary even within the same shape category.
Do these recommendations come from an optician? No — they're commonly-cited style heuristics gathered for reference, not personalized professional advice, and this site has no affiliate or product relationship with any eyewear brand.
Why is my shape not perfectly matching the table's "avoid" column in a style I already own and like? These are general guidelines, not rules — personal preference and how an individual frame actually sits on your face should take priority over a general heuristic.
