these pghrt.diy sticker designs are meant for stickers the same size as USPS Label 228.

it was a little tricky to do alignment on my printer, so there are two versions here:

sticker without padding (4.5" by 5.75")
sticker with some padding that helped my printer align things (Label 228 size, 4.5" by 5.75")

the raw files are also available here:
