Common questions
A WhatsApp status poster should be 1080 × 1920 pixels, a 9:16 portrait shape that fills the phone screen. In Poster Maker, pick the Story size. Keep your shop name and phone number away from the top and bottom edges, where WhatsApp shows its own buttons.
Use 1080 × 1350 pixels (4:5) for the most space in the feed, or 1080 × 1080 pixels (1:1) for a square post. In Poster Maker these are the Post and Square sizes. Instagram stories and reels covers use 1080 × 1920 pixels, the Story size.
For sharp print, use 300 DPI: multiply the paper size in inches by 300. An A4 poster is 2480 × 3508 pixels and A3 is 3508 × 4961 pixels. Paid Poster Maker plans download a print-ready PDF, which is the best file to send to a print shop.
No single size fits every place, but the 1:1 square (1080 × 1080 pixels) comes closest: it works on WhatsApp, Instagram and Facebook feeds. For status and stories, make a second copy in the 9:16 Story size — in Poster Maker that takes one tap.
