Reels compete in a full-screen, sound-on feed. Your job is to make the first frame legible, the hook immediate, and the captions readable even when Instagram draws handles, buttons, and promo labels over the edges.
Primary export target
Resolution: 1080 × 1920 · Aspect ratio: 9:16 · Orientation: vertical portrait.
This lines up with phone displays and minimizes odd scaling. If you shoot horizontal, plan your vertical reframe at storyboard time-not as an afterthought.
Alternate ratios teams sometimes test
| Aspect | Example pixels | When it appears |
|---|---|---|
| 9:16 | 1080×1920 | Default for short-form vertical. |
| 3:4 | 1080×1440 | Taller-than-wide; may letterbox in some viewers-verify previews. |
| 4:5 | 1080×1350 | Classic feed-friendly; can affect how clips feel when surfaced outside full-screen. |
Safe zones (practical, not pixel-perfect)
Think in layers:
- Top band: Leave space for the Reels chrome (profile, audio pill).
- Right edge: Likes/comments UI stack here on many devices.
- Bottom band: Captions, stickers, and CTA text often collide-raise critical copy.
- Center column: Default home for faces, product hero, and main subtitles.
Because devices differ, preview on a small phone after export, not only your editing monitor.
Thumbnail / cover strategy
Grid visitors judge your brand from cover tiles. Tips:
- Use high contrast between subject and background.
- Limit on-image words to 3–5 words max.
- Maintain a series visual language (color bar, icon, episode number).
- Avoid placing text where the profile grid crops on profile previews.
Caption & hashtag discipline
Reels captions support discovery, but stuffing keywords looks spammy to humans and can dilute message fit. Prefer:
- One primary topic per Reel
- Plain-language hooks in the first line
- Branded hashtags where campaigns require tracking
Cross-post checklist (Reels + TikTok)
If you reuse a vertical master, read TikTok export settings and adjust captions for platform tone. Remove “link in bio” language on TikTok when it does not apply, and vice versa.
QA before scheduling
- Hook lands in the first 1–2 seconds.
- On-screen text is readable at 50% phone brightness.
- Music/dialogue passes a cheap headphone test (not only studio monitors).
- Cover frame reads as a still image-no mid-blink leader frame.
Frequently asked questions
- What size should Instagram Reels be?
- Export 1080×1920 at a 9:16 aspect ratio for full-screen Reels. That is the most common professional deliverable in 2026.
- Does Instagram support 3:4 or 4:5 for Reels?
- Alternate aspect ratios may upload and display with letterboxing or crops depending on surface. When Reels distribution matters, default to 9:16 and test previews before scheduling.
- How long can a Reels video be?
- Maximum duration changes over time and can vary by account. Confirm inside the Instagram camera/ composer and official Help before building a 3-minute narrative around an outdated cap.
- Do I need a cover image for every Reel?
- Not always, but a deliberate cover improves grid cohesion-and some accounts rely on readable cover typography for series branding.
