what should be the size of a twitter background?

[Shubham]

I m going to make my own twitter header and background so size of a twitter header is 1252x626 that size fit exact in header but 4 the background i tried the size 1024x768 but that was too small and then i tried 1920x1200 but that was too big, so what's the exact size of a twitter background?

The smallest size to make a background should be 1600w x 900h pixels (or 22.222 inches by 12.5 inches). But if you have a huge image that can fit, the size that would accommodate just about all screen resolutions would be 2500w x 1600h pixels (34 inches by 22 inches).
