Face shape guide
An oval face is about one and a half times longer than it is wide, widest at the cheekbones, with a jaw a little narrower than the cheekbones and a softly rounded chin.

How to tell
What the detector scores
Oval has no forehead or lower-jaw rule: it is defined by sitting in the middle on the three readings above. Bands are the ones the Face Shape Detector uses on uploaded photos; width is measured at the cheekbones, forehead at the temples, length from an estimated hairline to the chin.

Often confused with

Oblong
Same widths, more length. Oblong starts scoring at a length : width over 1.50 and scores fully over 1.55, with a jaw angle under 108°. Oval sits at 1.38 to 1.52 with a jaw angle of 108° to 116°.

Round
Shorter and softer. Round needs a length : width under 1.38 and a jaw angle over 125°. An oval keeps 1.38 to 1.52 and a jaw angle of 108° to 116°.

What fits
Conventional advice, stated in terms of the ratios above: frames and volume either add width where the face is narrow or add length where it is wide.
Bone vs soft tissue
Face shape is mostly bone. The distance from the hairline to the chin, the width across the cheekbones and the width at the temples are set by the skull and do not move. The jaw readings, the jaw : face width and the jaw angle, sit under soft tissue: fluid, fat and the masseter all change them by a few points, which is enough to move a face across a shape border.
Oval is mostly bone: the cheekbone width and the distance from the hairline to the chin do not move. What drifts is the jaw ratio. Fluid in the lower face after salt, alcohol or a poor night widens the jaw : face reading toward round, and uneven masseter tone from chewing on one side can pull the jaw angle a couple of degrees off. That is why the same face can read oval in the morning and closer to round in the evening.
FAQ
No shape is. Oval gets called ideal in magazine guides because most frames and haircuts sit well on it, which is a styling convenience, not a ranking. Shape is a description of ratios, and the detector reports it that way.
The bone does not, so an oval stays oval. Weight, fluid and jaw muscle tone change the jaw : face ratio and the jaw angle by a few points, which can move a borderline oval toward round or oblong on a given day. The length and the cheekbone width stay put.
Because oval sits in the middle of the ranges, it borders round on one side (shorter, wider jaw) and oblong on the other (longer, tighter jaw angle). A length : width near 1.38 or 1.52, or a jaw angle near 108° or 116°, scores points for both. The second bar tells you which way you lean.
Yes, if it hides the temples or the jaw. The detector estimates face length from the glabella and chin, so a fringe does not change the length, but hair over the temples changes the forehead reading and a full beard hides the true jaw width. Pull the hair back and, if you can, photograph the jawline uncovered.
