The 250kb Club is a collection of web pages that focus on performance, efficiency and accessibility.

Websites in this list must not exceed 256kb compressed size!

Yes, compressed size. It makes much more sense because it allows for a lot of text to be transferred without having a big impact on the total size, while the impact of media is basically unaffected.

If your pages exceeds 250kb, you might consider 512kB.club or 1MB.club.
