The desktop editions do not have a set upper limit, but your computer will eventually run out of memory. The point at which this becomes unworkable will vary, depending on what you want to do, what your painting is using, and how powerful your computer is.
If you’re using the latest desktop version (4.5), it has 64 bit support and can work at very large file sizes, easily up to 15,000 pixels on most computers. It can save larger files, but is limited by your computer memory and speed, so you may have trouble working with files larger than that.
If you’re using ArtRage 4.0.6 or earlier, the maximum canvas size isn’t limited, but the lack of 64 bit support means that most computers will struggle with larger sizes. 8,000-10,000 is the practical upper limit for most people. You can create larger canvases, but you may encounter very slow working speeds and instability.
If you’re using one of the mobile editions, then the maximum canvas size is capped at 2048 x 2048 with a few exceptions.
- ArtRage for iPad on iPad Pro 11″: 4096 x 4096
- ArtRage for iPad on iPad 1 devices: 1400 x 1400
- ArtRage for iPhone: 960 x 640
Tips for Creating Larger Canvases
- Start with a smaller area and then expand the canvas as you work
- Fill large areas (e.g. backgrounds) at smaller sizes, then resize the canvas.
- Avoid memory intensive tools (e.g. Transform, Watercolors, the Soft Palette Knife)
- Create a smaller canvas, collapse all the layers and resize it upwards, then touch up any fine details
- Record your painting as a script (available in ArtRage Studio Pro, ArtRage 4 and ArtRage for iPad) and then play it back at a larger size in ArtRage Studio, ArtRage Studio Pro and ArtRage 4.
