Designed it with my Galaxy S9+ in mind but it works with Galaxy S8+ given they're are very similar in size (other phones with similar size should work as well).

I tested it with other smaller phones like iPhone SE (2nd Edition) and iPhone 6S with success. It should be reasonably sized for almost all phones generally speaking.

I gifted a friend who has an iPhone XS Max and fitted nicely.
