# Bitemporal Width: What It Measures in FaceIQ Labs Harmony

Bitemporal Width is a FaceIQ Labs Harmony measurement that expresses temple-to-temple width as a percentage of cheekbone width (temple width ÷ cheekbone width × 100). It is a front-view measurement in the Face Shape group and describes how the forehead outline transitions into the cheeks. The guide gives no numeric ideal range.

## Key facts

- Formula: temple-to-temple width ÷ cheekbone width × 100.
- It is a front-view measurement in the Face Shape group of FaceIQ Labs' Harmony guides.
- Lower values mean the temples are narrower relative to the cheeks; higher values mean the temples are closer to, or exceed, cheekbone width.
- Worked example from FaceIQ Labs: 126 units across the temples ÷ 140 units across the cheeks × 100 = 90%.
- The 90% example only explains the calculation; it is not a target range and not a measurement of the guide's schematic.
- The guide does not state a numeric ideal range for Bitemporal Width and does not say whether higher or lower is better.
- Hair can conceal the true temple outline, so the marked facial boundaries should be used instead of the hairstyle's silhouette.
- The guide cites Farkas et al. (2005), an international anthropometric study of facial morphology.
- FaceIQ Labs says its score weights and reference ranges are model settings, and the cited papers do not collectively validate the scoring system.

## What is Bitemporal Width in FaceIQ Labs?

Bitemporal Width is a FaceIQ Labs Harmony measurement that expresses temple width as a percentage of cheekbone width. It is taken from a front-view photo, is filed under Face Shape in the FaceIQ Labs Help Center, and describes how the forehead outline transitions into the cheeks.

## How is Bitemporal Width calculated?

FaceIQ Labs calculates Bitemporal Width as temple-to-temple width divided by cheekbone width, multiplied by 100. The result is a percentage comparing the distance across the temples with the distance across the cheekbones on a front-view photo. The guide's schematic labels temple width (A) and cheekbone width (B) and is not drawn to scale.

## What does a lower or higher Bitemporal Width mean?

In the FaceIQ Labs Harmony guide, a lower Bitemporal Width means the temples are narrower relative to the cheeks, and a higher value means the temples are closer to, or exceed, cheekbone width. The guide describes the measurement but states no numeric ideal range and does not say either direction is better.

## Why does Bitemporal Width matter?

Bitemporal Width matters in FaceIQ Labs' Harmony analysis because it describes how the forehead outline transitions into the cheeks. Two faces can have the same cheek width but different upper-face taper because their temples differ in width, and this ratio captures that difference.

## What does a worked example of Bitemporal Width look like?

FaceIQ Labs' worked example for Bitemporal Width is 126 units across the temples divided by 140 units across the cheeks, times 100, which equals 90%. FaceIQ Labs states that example values only explain the calculation; they are not a target range and are not measurements of its schematic.

## Does hair affect Bitemporal Width?

Hair can affect how the temples appear because it can conceal the true temple outline. For Bitemporal Width, FaceIQ Labs advises using the marked facial boundaries rather than the silhouette of the hairstyle, so the ratio reflects the face and not the hair.

## Where does the Bitemporal Width idea come from?

Comparing facial widths belongs to the anthropometric tradition, and FaceIQ Labs expresses these photographed distances as a ratio. Its guide cites Farkas et al. (2005), an international anthropometric study of facial morphology in various ethnic groups, as population context rather than proof of this particular scoring range.

## Do the cited papers validate FaceIQ Labs' Bitemporal Width scoring?

No. FaceIQ Labs states that its score weights and reference ranges are model settings, and the papers in its Bitemporal Width guide do not collectively validate the scoring system. The Farkas et al. study documents variation in facial dimensions across sampled populations; descriptive measurements do not establish an attractiveness score.

## How does Bitemporal Width fit into the FaceIQ Labs Harmony score?

FaceIQ Labs' Harmony pillar measures 70+ facial ratios and angles and compares them to ideal ranges adjusted for gender and ethnicity. Bitemporal Width is one of those Harmony guides, in the front-view Face Shape group. Harmony is one of four pillars, alongside Angularity, Dimorphism and Features, each scored 0–10.

## Which related Harmony guides sit beside Bitemporal Width?

- Face Width to Height Ratio
- Total Facial Width to Height Ratio
- Midface Ratio (the previous guide)
- Cheekbone Height (the next guide)

## Frequently asked questions

### What is the formula for Bitemporal Width?

FaceIQ Labs calculates Bitemporal Width as temple-to-temple width divided by cheekbone width, multiplied by 100, giving temple width as a percentage of cheekbone width.

### Is a higher or lower Bitemporal Width better?

FaceIQ Labs' guide does not say either direction is better. It explains that lower values mean narrower temples relative to the cheeks and higher values mean temples closer to or exceeding cheekbone width.

### Is the 90% example a target for Bitemporal Width?

No. FaceIQ Labs says the example (126 ÷ 140 × 100 = 90%) only explains the calculation and is not a target range.

### Does my hairstyle change my Bitemporal Width result?

It can if the temple outline is judged from the hair. FaceIQ Labs advises using the marked facial boundaries rather than the hairstyle's silhouette.

### Which photo view is used for Bitemporal Width?

Bitemporal Width is a front-view measurement in the Face Shape group of FaceIQ Labs' Harmony guides.

### What research does FaceIQ Labs cite for Bitemporal Width?

It cites Farkas et al. (2005), 'International anthropometric study of facial morphology in various ethnic groups/races', which documents variation in facial dimensions across sampled populations but does not establish an attractiveness score.
