Where your ads run: places, sizes and text lengths

• Facebook feed and Instagram feed: 1080×1350 (4:5). Headline up to 40 characters, primary text up to 125 before "See more".

• Stories & Reels, on Instagram and Facebook: 1080×1920 (9:16), full screen. The top fifth and the bottom quarter stay clear of text, where the app's buttons sit.

• TikTok: 1080×1920 (9:16), full screen. Ad text up to 100 characters; TikTok shows no headline.

• Snapchat: 1080×1920 (9:16), full screen. Headline up to 34 characters.

• Pinterest: 1000×1500 (2:3). Title up to 40 characters, description up to 100.

• Google Display: 1200×628 (1.91:1). Headline up to 30 characters, description up to 90.

• LinkedIn: 1200×1200 (1:1). Headline up to 70 characters, intro text up to 150.

• X: 1200×1200 (1:1). Card headline up to 70 characters, post text up to 200.

• YouTube Shorts (9:16) and YouTube (16:9) take video ads only.

How it works

• Pick several places for one batch: each ad renders once per size they need, so a feed and a Story make two pictures of the same ad. The batch counts pictures.

• The copy fits the strictest place you picked: with TikTok and Facebook together, the primary text stays under 100 characters.

• The engines render on their own grid (3:4, 9:16, 16:9, 1:1); the download crops each picture to the exact size of its place, centred.

• A video ad takes one place at a time: its frame becomes the clip's.
