About PSL Scale
PSL Scale is an online facial-proportion analysis tool that explains what can be measured in a single front-facing photo. Choose a clear photo to receive a free, broad 0-8 PSL-style reference range, four proportion summaries, visible observations, and a photo tip without signing in.
The analysis reviews left-to-right balance, vertical facial thirds, horizontal spacing, and the relationship between visible face length and width. It checks photo suitability and explains how camera angle, distance, and lighting can affect the result. An optional detailed report adds context and explanations of the same measurements.
Use PSL Scale to understand a result or compare your own photos under similar conditions. PSL is a community convention with no official formula; the estimate is not a medical assessment, a validated attractiveness percentile, or a measure of personal worth.
