# Social Media Image Best Practices — 2025

## Choose the Right Format

| Format | Best For | Avoid When |
|--------|----------|------------|
| **JPG** | Photos, complex imagery, backgrounds | Need transparency |
| **PNG** | Logos, graphics with transparency, text-heavy images | Large photos (file size) |
| **WebP** | Web delivery (smaller than JPG/PNG) | Platform doesn't support it |
| **GIF** | Short looping animations | High quality is required (256 colour limit) |
| **MP4** | All video content | — |

## Compression Guidelines

- Target **72–150 dpi** for web; higher resolutions add file size without visual benefit
- Keep images under **1 MB** where possible for faster load times without quality loss
- Use tools like Squoosh, TinyPNG, or ImageOptim before uploading
- Always use **sRGB** color profile — CMYK images render incorrectly on screens

## Safe Zones

Every platform reserves UI space (navigation bars, profile info, CTAs) that can obscure your image. Keep key visuals and text inside these safe zones:

| Platform  | Content Type | Safe Zone                    |
|-----------|--------------|------------------------------|
| Instagram | Story/Reel   | Center 1080 × 1420 px        |
| Facebook  | Story        | Avoid top 14% and bottom 20% |
| TikTok    | Video        | y: 150 – 1770 px             |
| Snapchat  | Snap/Ad      | Center 1080 × 1420 px        |
| YouTube   | Banner       | Center 1546 × 423 px         |

## Aspect Ratio Decision Guide

| Aspect Ratio | Common Use | Why |
|---|---|---|
| **9:16** (vertical) | Stories, Reels, TikTok, Shorts | Full-screen mobile; highest immersion |
| **4:5** (portrait) | Instagram/LinkedIn feed | More feed space than square; best engagement |
| **1:1** (square) | Universal feed posts | Safe crop on all platforms |
| **16:9** (landscape) | YouTube, X posts, article covers | Standard widescreen; desktop-friendly |
| **1.91:1** (wide) | Facebook/LinkedIn feed, Twitter cards | Standard link preview ratio |
| **2:3** (tall) | Pinterest Pins | Pinterest column format |

## Accessibility

- Ensure text in images has a **contrast ratio ≥ 4.5:1** against the background (WCAG AA)
- Don't rely on images alone to convey critical information — include alt text and captions
- Use readable fonts at a minimum **28–32 px equivalent** for Story/Reel text overlays
- Add closed captions to videos — most platforms auto-generate them but review for accuracy

## Consistency & Branding

- Use consistent padding and margins around your logo (typically 5–10% of image width)
- Maintain the same color palette and font stack across all platforms for brand recognition
- Create templates at each canonical size so the team doesn't have to remember dimensions
