I've also come across 120 X 60 (very rare) and for top sites directories there's also a 480 x 100 one. I hate the really small ones though because it's hard to make them look great and still fit text on them.

i was frustrated by the size as well, it's not the most convenient thing. i think i was interested in doing a 90x30 revival before i started archiving buttons. 100x50, you say? that seems like something fun to experiment with for higher-res buttons... i'll look into it

(also wow i did not expect to be linked at the bottom of that 88x31 article!! thanks neonaut!!)

The sizes I've mentioned were probably invented by the fanlistings community, but they have certainly been used on fan sites quite a lot, and the personal sites of those who make fanlistings. I remember making some really mis matched ones (size wise) when I first started making fan sites because I didn't realise people could crop images. Pixel fonts are used a lot on them too.

I believe for modern screens, we really need a new standard to replace 88x31, but I'm not sure how it can be agreed upon by a wide community.

I agree the 88x31 is too small and a bit annoying to design. I briefly wondered if the Hosted by Neocities button could provide inspiration, but it's an odd size (200x59). I think something like a 100x50 banner exchange has a chance of trending here on Neocities though.

2OO x 59 is a bit too big in my opinion. Just tested it out and I can't see a page of those side by side. I think 100 x 50 has the advantage because it's commonly used among fanlistings and if folks who do that make a site here then they'll probably use it. (The drawback is lack of php and database sites - most FLs these days use that to manage them, but a fan site which doesn't need it could work.)
