Frequently asked questions about the 99×210 mm postcard
Why 99×210 mm – what is this size?
99 × 210 mm is the so-called DL size, which is one third of an A4 sheet. It matches the dimensions of a DL envelope, which makes the postcard easy to mail – the card slides into the envelope without any folding.
Does the postcard fit a DL envelope without folding?
Yes. The interior of a DL envelope is slightly larger than 99×210 mm, so the postcard slides in as-is. This is the biggest advantage of the format for direct mail – you can post the card in an envelope without any folding or special handling.
How fast can 99×210 mm postcards be printed?
aDigi is an agile digital print shop in Helsinki. The production time is selected at checkout, and the fastest option is 1 working day with a print-ready PDF.
Which board weight works best for a slim postcard?
For this elongated format we recommend at least 300 g, so the card stays straight and doesn't bend from the longer side. The 330 g postcard board or 400 g matte are ideal – they feel substantial in hand and survive postal handling.
Can I order the card in portrait or landscape orientation?
Both work. The orientation is selected at checkout. Portrait suits save the date cards and menu cards, while landscape works well for direct mail and festival promotion.
