CATDOLL How to Choose BJD Eyes: Diameter and Iris Size

A guide to eye sizing, placement and the look created by different irises.

Two measurements matter

Eye diameter describes the overall eye; iris size influences the visible gaze. Two eyes with the same outer diameter can look very different if their irises are differently sized. The eye opening, head sculpt and intended character determine which result feels balanced.

Start with the sculpt, not a trend

Check the head maker’s recommended range, then compare sample photographs from the front and three-quarter angles. A large iris can create an innocent or stylized expression; a smaller iris may make the gaze appear more focused. Personal taste matters more than a rigid rule.

Secure without damage

Use an eye putty or mounting method suitable for the head material, applied according to the maker’s guidance. Avoid products that stain, become difficult to remove or react with painted surfaces. When adjusting the gaze, use gentle pressure and support the head safely.

Photograph before deciding

Place both eyes at the intended depth and photograph them in soft, even light. Adjust the gaze in small steps; an expression can change dramatically with a minor shift. Save a comparison image before buying extra eye sets so you can learn which proportions you prefer.
