Source conflict
Instagram Stories resolution has three different Meta answers
The Ads Guide and the Help Centre contradict each other directly; the third figure is a cross-placement minimum.
| Source | Value | Type | Accessed |
|---|---|---|---|
| Meta Ads Guide · Instagram Stories, video and image | 1440 x 2560 px | Design recommendation | 5 Aug 2026 |
| Meta Business Help Centre · Design requirements for Instagram Stories ads | 1080 x 1920 recommended · 600 x 1067 minimum | Design guideline | 5 Aug 2026 |
| Meta Business Help Centre · Recommended minimum image pixel requirements across placements | 1080 x 1080 px minimum | Design guideline | 5 Aug 2026 |
What to use
The Ads Guide figure, 1440 x 2560, is the placement page's own and matches every other Meta vertical placement checked. The 1080 x 1080 row is a minimum shared across placements, not a target. No Meta page reconciles the first two.
