The size for an Expo app on iOS is approximately 33mb (download), and Android is about 20mb. This is because Expo includes a bunch of APIs regardless of whether or not you are using them – this lets you push over the air updates to use new APIs, but comes at the cost of binary size.

If you want to upload it in play store then it much better that you run expo build:android -t app-bundle and upload it . At play store bundle reduce their size approx. 30-40% of its actual size. If you want to run build directly to your android without uploading play store then you need to run expo build:android -t apk.
