Frequently asked questions
What does it cost to use these Theoretical Wallpapers?
No payment is involved. Skip the sign-up; it is not needed. Nothing is downgraded to sell you an upgrade.
How many Theoretical Wallpapers do you have?
The page lists 47 Theoretical Wallpapers. New work is published once it passes checks. Every one is free, with no account needed.
Will these Theoretical Wallpapers fit a phone as well as a monitor?
Both, as it happens. 55 run wide; 5 run tall. Take the wide ones for a monitor and the tall ones for a handset.
Are these Theoretical Wallpapers big enough for a large monitor?
The biggest version measures 5000x2619. That is enough for 4K screens. The smaller variants are cut ahead of time, so you never resize anything yourself.
