Measurements first. Explanation second.
Every reference starts with the exact dimensions, then adds pixels, ratios, use cases, printer notes, and comparisons. No padded introductions.
Reference library
Start with the sheet in your hand.
Every guide includes exact units, common DPI targets, a proportional specimen, regional notes, and practical print guidance.

Envelope library
Know what fits before you fold.
C-series and DL guides pair finished dimensions with the paper they hold, folding direction, production cautions, and postal context.
C4 envelope size
One or more A4 sheets at 210 × 297 mm, unfolded.
C5 envelope size
A5 at 148 × 210 mm flat, or A4 folded once to A5.
C6 envelope size
A6 at 105 × 148 mm flat, or A4 folded twice to A6.
DL envelope size
A4 folded into thirds to roughly 99 × 210 mm.
