Can this calculator predict my baby's exact eye color?

No, the tool provides probability estimates based on parental eye colors and population genetics. Actual eye color depends on complex polygenic inheritance and can vary even with the same parental inputs.

Do I need to know my or my partner's genetic eye color details to use this tool?

No, you only need to select the visible eye color from the provided options (Brown, Hazel, Green, Blue, or Gray). The calculator maps these to common genetic patterns.

Why do the percentage chances add up to approximately 100%?

The probabilities are derived from population-level research on the HERC2/OCA2 genetic region, which is the main regulator of eye color, though other pigmentation genes also contribute to the final outcome.

Is the result affected by grandparents' eye colors?

The calculator primarily uses the visible eye colors of both parents. While grandparent eye color can influence genetic potential, this tool focuses on parental phenotypes for its probability estimates.

About this tool

What Baby Eye Color Calculator does

A baby eye color calculator that estimates the probability of a child's iris color based on the visible eye colors of both parents. The tool presents a range of likely outcomes—brown, hazel, blue, green, or gray—along with percentage chances and brief explanations of the underlying genetics. Users receive an immediate, on-page result that includes the most likely color, percentage probabilities, and notes on the genes involved, all without requiring an account or payment. The interface updates live as selections change, making the process straightforward and accessible.

Is it right for you

Best for

Expectant parents or curious family members who want a quick, easy-to-understand estimate of potential baby eye colors based on parental traits, without needing genetic expertise or paid software.

Limitations

Results are probability estimates based on population-level genetics, not definitive predictions of actual eye color
Eye color is a polygenic trait influenced by many genes beyond the primary ones listed, so outcomes can vary
The tool relies on visible parental eye colors rather than specific genetic genotypes, which may limit accuracy for some family histories
