Sociala posters: ett koncept, alla plattformar
Mallar och säkerhetszoner för feed och Story.
The pain point for ops teams is rarely “can’t draw”—it’s one campaign needing five sizes, three copy variants, and two languages. AI Image 2 shines with accurate text + switchable ratios + Thinking batches. This tutorial gives you a copyable social poster production line.
Platform size quick reference (2026 common)
| Platform | Use | Ratio | Notes |
|---|---|---|---|
| WeChat / blog header | Cover | 2.35:1 or 16:9 | Title in center safe zone |
| Weibo / X feed | Post | 16:9 / 3:2 | Keep corner badges off edges |
| Xiaohongshu / Pinterest | Cover | 3:4 | Title in upper half |
| Instagram post | Feed | 1:1 | No critical info in corners |
| Story / vertical video | Full screen | 9:16 | Avoid top/bottom 12% UI overlap |
| LinkedIn post | Feed | 1.91:1 | Slightly corporate realistic |
Pick a master KV at 16:9 or 3:4 first, then derive other sizes.
Workflow overview (90 minutes per campaign)
Brief sheet → Thinking master KV → curate pick 1 → ratio switch derivatives → local copy edits → export naming → schedule upload
Step 1: Campaign brief sheet (copy template)
| Field | Example |
|---|---|
| Campaign | Mid-year sale 618 |
| Main slogan | ”More Than Half Off” |
| Sub slogan | ”Jun 1–18 storewide” |
| Primary colors | #E63946 + #1D3557 |
| Must-show | Specified product shot style |
| Forbidden | Competitor names, unverified superlatives |
Step 2: Master KV prompt (3:4 cover example)
Thinking mode, social cover 3:4 portrait.
[Copy] Main headline "More Than Half Off" (large bold), subhead "Jun 1–18 storewide" smaller.
[Scene] Center product group: sunscreen + sunglasses, summer beach bokeh background,
brand accent #E63946, bright commercial photography, headline in upper third.
[Forbidden] Garbled text, watermarks, malformed fingers.
Generate 4 candidates → pick 1 for Step 3.
Step 3: Ratio derivatives (no creative rewrite)
Based on the previous image:
1) Change to 16:9 landscape, headline left, product right, for feed posts.
2) Change to 1:1 square, headline centered top, product centered, for Instagram.
3) Change to 9:16 vertical Story, headline shifted up 15% safe zone, product lower center.
Keep colors and product consistent each time.
Request three ratios in one message or split into three for stability.
Step 4: Multilingual variants
Layout identical to the previous image, only replace copy:
Title "SUMMER SALE", subhead "Up to 50% Off · Jun 1–18"
Japanese and Korean work the same way; for RTL (Arabic) prefer text-free image + localized overlay.
Step 5: Text-free version + post overlay (insurance)
Thinking mode, 3:4 summer beach product scene,
reserve upper 30% solid gradient whitespace for later typography,
no text at all.
Designers overlay brand fonts in Figma / Canva—change pricing on launch day without re-running AI.
Step 6: File naming and archive

Scheduling and A/B
| Version | Variable | Metric |
|---|---|---|
| A | Slogan emphasizes discount | CTR |
| B | Slogan emphasizes new arrivals | CTR |
| C | Model vs product only | Save rate |
Compliance reminders
- Avoid unverified superlatives like “best” or “#1”
- Promo dates and prices must match backend config
- Portrait rights: label AI faces or use faceless compositions

Today’s challenge
Pick a real campaign (even internal test) and deliver in 90 minutes:
- 1× 3:4 master KV
- 2× derived ratios
- 1× text-free backup
After that, your social poster output upgrades from “single-card luck” to a schedulable production line.
