How-to Guide
Combine Photos into a Grid for Twitter / X Posts
Twitter / X limits each tweet to 4 images. When you need to show more context — a step sequence, a multi-panel comparison, or a screenshot series — merging them into one grid image is the cleanest solution that keeps your thread readable and visually impactful.
Try MergeFrame — FreeX (formerly Twitter) displays image attachments in a fixed multi-image layout: 2 images side by side, 3 in an L-shape, and 4 in a 2×2. This is fine for casual photos, but it's not optimal when you need to show a specific visual narrative, a comparison, or a screenshot sequence.
By merging your images into a single grid before uploading, you take full control of the layout. Your images appear exactly as you arranged them, the crop and composition is yours, and the viewer doesn't have to figure out which image to look at first.
High-value use cases for Twitter/X grid images: (1) metrics dashboards — combine 4 analytics screenshots into one image to share a business update without file attachment limits, (2) product announcement — combine product UI screenshots at launch to tell the full feature story in one post, (3) live-event thread — merge 4 photos from the event into a grid for a visual event summary tweet, (4) before/after comparison — side-by-side transformation for tech, fitness, or design content.
Keep X grid images at 1200×675px (16:9) for landscape tweets or 1200×1200px for square. PNG is preferred for screenshots; JPEG for photography.

Choose a 1×2 or 2×2 layout
1×2 for a side-by-side comparison, 2×2 for a 4-image story grid.

Export at 1200×675px (landscape) or 1200×1200px (square)
These dimensions display optimally in X's tweet card layout without cropping.

Frequently Asked Questions
Does X/Twitter compress grid images?
Yes, X compresses images significantly. Upload PNG for screenshots to minimize compression artifacts. Use images at 2× your target display size to compensate for compression quality loss.
Will a grid image affect my tweet's reach on X?
Images in tweets generally increase reach compared to text-only tweets. A well-composed grid that visually hooks the viewer tends to generate more replies and retweets, which amplifies reach further.
Can I use a grid image in a pinned tweet?
Yes, and this is a highly effective strategy. A pinned tweet with a strong visual grid that summarizes your work, skills, or offering immediately communicates value to new profile visitors.
