Print, at 300 dpi
300 dots per inch is what most printers ask for. Multiply the size in inches by 300 to get pixels, or divide millimeters by 25.4 first.

Setting up a canvas in Rindraw
Choose New Drawing › Custom Canvas, then give the width and height in pixels, millimeters, centimeters or inches, with a resolution from 1 to 2400 dpi. Save it as a preset to use again. A3, A4, A5, US Letter, US Legal, 4 × 6, Square and 4K are built in.
A canvas can be up to 16,384 pixels a side. Drawing on the 2026 iPad mini? Its screen is 2316 × 1512 pixels; see drawing on the new iPad mini.
Why the size matters less in Rindraw
In most drawing apps the canvas size is the most detail you'll ever get: a sketch drawn at screen size stays at screen size. Rindraw keeps each stroke as the path you drew, so when you export at a bigger size it draws the strokes again at that size, sharp. Pick the canvas for its shape, then export as big as the print needs. Pictures you import are the exception: they're pixels, and stay at the size they came in.
For a series, such as a comic with several pages, frames can sit side by side on one canvas and leave as a PDF, a page each. Coming from Procreate? Your canvases come with you.
