How it works
Choose a size
Pick a ready-made size from the list, such as a hero, an Open Graph image or an ad slot, or type your own width and height. Lock the ratio to keep the shape while you resize.
Pick a colour
Use a suggested colour, a shade of your current colour, the colour picker, or type any hex, rgb or hsl value. The preview updates as you type.
Add a style if you want one
Keep it flat, add a soft gradient or a subtle pattern, and turn on a label that shows the size. The label is always black or white, whichever is easier to read.
Download
Choose PNG, WebP, JPG or SVG and press Download. The file is made on your device and named from the size and colour, so it is easy to find and replace later.

What is the 300 × 1050 size used for?
It is a very tall ad for high-impact placements where a site has room for a long column. It is listed under ad sizes in the ready-made sizes.
Should I make the 300 × 1050 image bigger?
For sharp results on high-density screens, use 600 × 2100 px, which is twice the width and height. Type those numbers into the size fields. Because it is more than three times as tall as wide, design in sections from top to bottom.
How heavy is a 300 × 1050 placeholder?
A flat-colour SVG of 300 × 1050 px is only about 143 bytes, small enough to paste as a data URI. A decoded raster version needs about 1.2 MB of memory, which is light for any device.
Can I choose another colour or format for 300 × 1050?
Yes. Choose any colour, a gradient, a pattern or a label, and save it as PNG, WebP, JPG or SVG. By default the file is called placeholder-300x1050-3b82f6.png. Ad networks set their own limits for file weight and format, so check their rules before you build the final creative at this size.
