Picking the right paper & envelope
For everyday office printing, 80gsm A4 is the workhorse — opaque enough for double-sided, runs cleanly through every printer, and gives you the best price per page. Step up to 100gsm for letterhead, proposals, contracts and anything client-facing. 70gsm has its place for high-volume internal printing where the paper gets thrown away the same day, but it can show through and jam older machines.
Envelope sizing is simpler than it looks: DLE (110×220mm) takes an A4 sheet folded in thirds — your standard letter and invoice envelope. C5 (162×229mm) takes A4 folded in half — use it for documents you don't want creased. C4 (229×324mm) takes A4 flat with no folding — for reports and anything with a stiff backing. Window envelopes save real time on bulk runs since the recipient address shows through from the letter inside.
For NZ schools, offices and high-volume mailers
Most school orders ship as a single consolidated delivery to one site, but we'll split-ship across campuses on request — just flag it at checkout. For mailrooms processing more than a few hundred items a week, our team can spec the right courier satchel sizes against your NZ Post or courier rate card to make sure you're not paying for empty space — most operations save 10–15% on shipping just by switching to better-fitting packaging.
