For a dependable 2026 social image workflow, start with the dimensions that are explicitly established, then verify any platform placement whose size is not listed. The confirmed examples here are an Instagram Reel at 1080 × 1920 pixels and a YouTube channel banner at 2560 × 1440 pixels recommended (minimum 2048 × 1152 pixels, 6 MB or less).
Social Media Image Sizes Cheat Sheet
| Platform | Asset | Verified Size Or Limit | Practical Use |
|---|---|---|---|
| Reel | 1080 × 1920 pixels | Use this canvas for a Reel export. | |
| YouTube | Channel banner | 2560 × 1440 pixels recommended, especially for TV; minimum 2048 × 1152 pixels; 6 MB or less | Keep important artwork inside the platform’s visible safe area when you verify the current guidelines. |
| Other placements | Not stated | Use SocialSizes to check the current pixel, aspect-ratio and safe-zone entry before exporting. | |
| Twitter/X, LinkedIn, Facebook, TikTok, Pinterest and other presets | Platform-specific assets | Not stated | Zeraku Social Asset Generator lists 15+ platform presets; confirm the output dimensions for the exact placement you need. |
How To Apply The Sizes
Start With The Exact Placement
Decide whether the file is a Reel, channel banner or another placement before resizing. A single platform name is not enough because each platform can have several asset types.
Check Pixels, Ratios And Safe Zones
SocialSizes provides exact pixels, aspect ratios, safe zones and free design templates. Its Instagram template download can place the available Instagram sizes in one template. If a needed placement is not explicitly listed, treat its dimensions as unknown and check the current platform guidance.

Checks Before You Publish
- Confirm the asset type, pixel dimensions and file-size limit for the exact placement.
- Preview text, logos and faces inside the stated safe zone before posting.
- Open a ZIP export and label each file by platform and placement so the wrong crop is not uploaded.
- The supplied information does not establish ownership or reuse rights for uploaded or exported artwork. Check each service’s terms and the destination platform’s rules before commercial publication.
