How to Make a Canvas Larger Than 36x36 Inches?

If you're designing a large-format sign or poster and need your canvas to exceed the 36x36-inch size limit, here's how to do it while maintaining a printable file that still looks sharp.

✅ Why There's a Limit

Corjl 2.0 limits canvas sizes to a maximum of 36 inches by 36 inches at 300 PPI (pixels per inch) to maintain high-resolution outputs suitable for professional printing. However, you can go larger by adjusting the PPI (also referred to as DPI — dots per inch).

📐 How to Make Your Canvas Bigger

To increase the physical size of your canvas beyond 36x36 inches:

1. Lower the PPI

   Drop the resolution to 180–200 PPI. This is perfectly acceptable for large signs and posters that are viewed from a distance.

   Recalculate Your Canvas Size

   For example:

   • 36 inches at 300 PPI = 10,800 pixels

   • At 180 PPI, that same pixel dimension equals 60 inches

     (10,800 ÷ 180 = 60 )

     So, setting your canvas to 10,800 x 7,200 pixels at 180 PPI would give you a 60"x40" printable file.

🧠 Why Lower PPI Works for Large Prints

Most large-format prints, like signage or posters, aren’t viewed up close like invitations or business cards. A resolution of 180–200 PPI is considered professional-grade for these kinds of designs, even with some detail included.

This standard comes from how people interact with posters — typically viewing them from several feet away, which makes a slightly lower resolution look perfectly crisp.

🎯 Summary

• Need more than 36x36 inches? Lower your canvas PPI.
• Use 180–200 PPI for high-quality large prints.
• Calculate canvas size by dividing your desired pixel dimensions by the PPI.
