If I wanted to share some space from my phone to my ipad am I able to do that?

Sorry but no. Space on iPads and iPhones is a physical thing and cannot be shared. However, iCloud storage can be shared across your devices. You may want to check that out.

Here is a link to info on how iCloud can be set up between devices:

Sign in to iCloud on all your devices - Apple Support

Here is a link showing pricing for iCloud+ Which provides more storage and additional benefits. Tap the Upgrade to iCloud+ button to see the details. You don’t have to sign up if you decide not to sign up.
