Using this tool

Toggle features and adjust the asset and font quantities to explore a rough size budget. The displayed feature weights are illustrative assumptions, not measured SDK sizes.

What the output does not tell you

This model does not predict a store download size or a platform difference. Dependencies can overlap, and release settings, device architecture, compression, and store processing affect the actual result. Measure a release build before making a size commitment.
