How-to Guide

Free Grid Maker for All Social Media Platforms

Every social platform wants a different image size, but building a grid is the same process everywhere. One tool, any layout, any export size: MergeFrame adapts to whatever platform you're posting on.

Social media managers juggle multiple platforms: Instagram 1080², Pinterest 1000×1500, LinkedIn 1200×627, Facebook 1200×630, Twitter/X 1200×675, TikTok 1080×1920, YouTube 1280×720.

Build your grid once in MergeFrame, then export at each platform's dimensions. The layout stays the same: only the resolution changes.

For cross-platform campaigns: build a master grid at 2000px (format carré), then crop and resize per platform. This ensures brand consistency while meeting each platform's technical requirements.

Platform export presets: Instagram feed = 1080², Stories = 1080×1920, Pinterest = 1000×1500, LinkedIn = 1200², Facebook = 1200×630, Twitter = 1200×675, YouTube = 1280×720.

Frequently Asked Questions

Do I need different tools per platform?

No. MergeFrame works for all. Build once, export at different resolutions.

Highest export resolution?

4000px on every plan, free included. That ceiling is the same whether you're on free, a 24h Pass, or Pro: paid plans lift the daily export limit, not the resolution.

Same grid on every platform?

Same layout is fine. Optimize the caption: hashtags for IG, professional context for LinkedIn, concision for Twitter.
