Which sunglasses
suit your face?

Shape decides what flatters. Width decides what fits, and width matters more. This range is one rectangular frame in five tints, so it cannot offer a shape for every face. What follows is the general rule for each, and an honest note about where a 140mm rectangle lands.

Round Width and length are close, the cheeks are the widest point, and the jaw curves rather than turns. Add a straight line. Angular frames and a strong browline give the face a horizontal it does not have.
Square The forehead, cheekbones and jaw are close to the same width, and the jaw turns a corner. Soften and lift. Curves and a frame that sits high take the edge off a strong jaw.
Oval Longer than it is wide, with a gently rounded jaw and a forehead slightly wider than the chin. Almost anything fits. The only real rule is proportion: keep the lens no deeper than the face can carry.
Heart A wide forehead and cheekbones narrowing to a fine chin. Balance the top. A frame wider at the base than the brow, with light rims up top, evens the taper.
Diamond Narrow forehead and jaw with wide, high cheekbones as the widest point. Widen the brow. Frames with detail or lift along the top rim bring the eyes level with the cheekbones.
Oblong Noticeably longer than wide, with a straight cheek line and a forehead and jaw of similar width. Break the length. A deeper lens and a decorated or contrasting temple cut the face horizontally.

The journal's face shape post puts the one rule behind all six shapes in plain terms, and explains why width matters more.

Where a rectangle fits in

A rectangle with a flat brow is a strong horizontal line, which is the classic counterweight to a round or an oval face and sits comfortably on a heart or a diamond. On a square or a very angular face it doubles down on a line that is already there, which some people want and some do not. The harder limit is width: at 140mm across, this reads as oversized on a face narrower than about 125mm, and no tint fixes that. If that is you, this range may simply be the wrong shape, and it is better to hear it here than after it arrives.

There is a second reason this is one page rather than six. Six near-identical pages, each recommending the same five products under a different face-shape heading, is a doorway: it exists to catch search traffic rather than to answer anyone. When the range holds more than one shape, this becomes six real pages.

Questions, answered

What suits a round face?

Add a straight line. Angular frames and a strong browline give the face a horizontal it does not have. Small round frames, which repeat the shape instead of answering it.

What suits a square face?

Soften and lift. Curves and a frame that sits high take the edge off a strong jaw. Heavy square frames, which double the angle already there.

What suits a oval face?

Almost anything fits. The only real rule is proportion: keep the lens no deeper than the face can carry. Frames deeper than the distance from brow to cheekbone, which shorten the face.

What suits a heart face?

Balance the top. A frame wider at the base than the brow, with light rims up top, evens the taper. Top-heavy browlines and decorated upper rims, which widen the widest part.

What suits a diamond face?

Widen the brow. Frames with detail or lift along the top rim bring the eyes level with the cheekbones. Narrow frames that sit inside the cheekbone line and make it wider still.

What suits a oblong face?

Break the length. A deeper lens and a decorated or contrasting temple cut the face horizontally. Shallow lenses and small frames, which leave the length unchallenged.
