FAQ – Some people find the measurements of watercolour paper a bit confusing. Here is a little summary that might help.
Loose sheets of watercolour paper often come in Imperial sizes while pads and blocks of watercolour paper usually come in European (ISO) A sizes.
A sheet of Imperial (also called Full Imperial) is 30×22 inches (76x56cm).
We offer a free cutting service for our watercolour papers. We can cut sheets in half (15×22 inches) or quarters (11×15 inches) on request. Paper stretchers are often made to accommodate Full, Half or Quarter Imperial sized paper, but we have one that will take A4.
A Full Imperial sheet of paper is a bit smaller than A1 which is 84.1×59.4cm.
The other A sizes are based on half of the larger size above it.
A2 is 42×59.4cm
A3 is 42×29.7cm (the size of the Jackson’s catalogue open)
A4 21×29.7cm (the size of our Jackson’s catalogue closed)

Hi Katherine.
Glad you found it helpful.
I have added to it a link to our glossary definitions of Art Papers, as well.
