I have included most standard paper sizes to Print to Size’s built-in list. But if you find that your paper size is missing you can use this page to add it to the app.
- View this page on your iPhone/iPad
- Fill-in the form below with your paper size
- Tap on the Add Size button
- Tap Open Print to Size
- The app now includes your size at the bottom of the paper size list
Once added I cannot promise that your printer will accept this new paper size: some printers only accept standard sizes and reject any other size. But if this works and you think the size should be included for everyone, please let me know and I will look into it – thank you!
