Poster guidelines

Setting the canvas in your design tool

• Canva: Create a design → Custom size → 1080 × 1350 px. Download as JPG.
• Figma: Frame → 1080 × 1350. Export at 1×, JPG, quality 85.
• Photoshop: New document → 1080 × 1350 px, 72 ppi, RGB. Save for Web → JPEG.
• Instagram post you already made: if it is already 4:5 portrait, it will be accepted and resized automatically.

What happens after you upload

1. 1. The browser checks the ratio before anything is sent. Wrong ratio → rejected on the spot.
2. 2. Correct ratio but off-size → automatically resized to 1080 × 1350.
3. 3. A 540 × 675 WebP thumbnail is generated and used on every event card.
4. 4. Both files are stored under posters/<CLUB_ID>/<EVENT_CODE>/.
5. 5. The core team reviews the event and publishes it.
