Choosing eyewear for a inverted triangle face comes down to one question: does the frame's shape work with or against the face's existing lines? An inverted triangle face carries the most width at the forehead and temples, narrowing sharply through the cheekbones to a fine, sometimes delicate jaw and chin. It differs from a heart shape in that the taper is generally more linear and the chin is less sharply pointed. Aviator Frames — teardrop-shaped lenses, thin metal frame, double bridge, wider at the bottom. — interacts with that geometry in a specific, predictable way.
The Visual Effect
The visual effect: Adds width and softness at the lower face and cheekbone area. On a inverted triangle face, where broad, the clear widest point of the face and notably narrow, often the face's most delicate feature, this effect either corrects an imbalance or reinforces the face's existing character, depending on which measurement the frame emphasizes.
Why This Pairing Works
Why this pairing makes sense: Minimize width at the forehead and temples while building width or structure at the jaw, using volume, texture, or facial hair to bring the lower face into closer proportion with the upper face. Frames that are faces that narrow toward the jaw and benefit from lower-face width are the ones worth trying first on a inverted triangle face; frames that are faces already wide or heavy at the jawline are worth trying on, but expect a less flattering result without careful sizing.
Sizing It Correctly
Sizing it correctly: The frame width should roughly match your face's widest measurement — for a inverted triangle face that's the cheekbones area. Frames noticeably narrower than that measurement will look pinched; frames noticeably wider will overwhelm the face rather than balancing it.
