The square placeholder
A square (1:1) placeholder is the right shape for anything that needs equal width and height: profile avatars, app and favicon icons, product tiles, and square social media posts. Because the two sides match, a square fits neatly into grids and circular crops.
This page opens already set to a 600×600 square. Type a different size to make a larger or smaller square, change the colours and caption, then download a square PNG or a scalable SVG.
How to make a square placeholder
- Open the page. The generator starts as a 600 × 600 square.
- Resize and style. Type any size (the 1:1 preset keeps it square), then set the colours and label.
- Download. Save it as a square PNG or an SVG that scales to any size.
Common square sizes
Avatars are often 128×128 or 256×256; social posts are commonly 1080×1080; app icons range from 512×512 up to 1024×1024. Tap the 1:1 ratio preset to keep any size perfectly square.

Where the Square (1:1) placeholder is used
- This page opens at 600 × 600, but a square is defined by its 1:1 ratio, not a fixed size — type the same width and height (or tap the 1:1 preset) to mock up any square slot.
- Avatars are commonly 128 × 128 or 256 × 256, square social posts are typically 1080 × 1080, and app icons often range from 512 × 512 up to 1024 × 1024 — all 1:1, so swap the resolution to match the target.
- Because the two sides are equal, a square placeholder survives a circular crop (avatars, story rings) without losing important content the way a rectangle would.
- 1:1 is the safest feed shape for a social mock-up because it shows in full in profile grids and most feeds without being cropped to a different ratio.

Frequently asked questions
What is a square placeholder used for?
Avatars, app icons, favicons, product tiles, and square social posts — anywhere the width and height should match.
How do I keep it perfectly square?
Tap the 1:1 ratio preset, or type the same value for width and height.
Can I download it as PNG or SVG?
Yes — switch the export format before downloading. PNG gives you a normal raster image that works everywhere; SVG gives you a tiny vector that stays sharp at any size.
Where is my image processed?
The placeholder is generated in your browser, so the file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
