Bitemporal Width
1 min read · Updated October 4, 2026
The width across your temples compared with the width across your cheekbones.
What it is
Bitemporal width is the distance between the two sides of the forehead at temple level, shown as a percentage of cheekbone width. It describes how the upper face tapers into the cheeks.
How it's measured
The two temple points and the two cheek points are landmarks. The temple distance is divided by the cheek distance and multiplied by 100, all in a levelled frame.
How it's read
Temples a little narrower than the cheekbones give the face a gentle taper and are the usual reading of a balanced upper face. Temples nearly as wide as the cheeks give a boxier outline; much narrower temples can make the forehead look pinched.
What affects it
Hair covering the temples doesn't change the measurement, which is taken from landmarks on the face, but harsh side lighting can make landmark placement wander slightly. Soft, even front light gives the cleanest result.
