PrintDennSize guide
How big is it, really?
Every size we print, drawn to scale against each other
Millimetres are hard to picture. Each size below is shown at its true size relative to the others, with something real to compare it against. For an exact check, hold a ruler up — the measurements are the honest finished size after trimming.

Collages

Why the sizes are not exactly A4 or A5
A4 and A5 divide a sheet perfectly, leaving nothing spare. We print slightly smaller than that on purpose, so every print can be trimmed with a few millimetres of artwork to spare on each edge. That margin is what stops a thin white line appearing along the side of your print. We would rather give you a print a few millimetres narrower than one with a white sliver down the edge.
Paper
Everything is printed on 180GSM glossy photo paper. Thick enough to stand up on a wall without curling, glossy enough that colours stay deep rather than going flat and chalky.
A note on colour
Screens emit light and paper reflects it, so a print never matches a screen exactly. Deep blacks and bright neons in particular land slightly softer on paper. This is how printing works everywhere, not a fault — see our returns policy for anything genuinely misprinted.
