The small thermal printer takes 53 mm width or smaller, so “A9 size, 37 x 52 mm, 1.5 x 2 in”.
The big thermal printer takes Legal (216 x 356 mm) or smaller.
For context, A4 size is 210 x 297 mm, 8.3 x 11.7 in. (Width is the only important part tho, tbf.)

…. Ok now what would be great is https://www.globepackaging.co.uk/6-x-rolls-of-extra-strong-reinforced-gummed-paper-water-activated-tape-48mm-x-100m.html if the roll itself were smaller so I could print on that — wait, probably doesn’t have the whatever that thermal paper has. :/
