I have an H-frame easel. It's a sturdy wooden easel as it has served me well for 30 years already. It can be used for paintings up to 130cm tall. It is only 50cm wide, but that does not really matter. The largest painting I made on it was 120x120cm.
The beam sticking out at the top is rather long, which does not always work well in my upstairs room. So I put a bunch of short beams on the horizontal part. The canvas then sits on those beams.
I prefer standing while painting, but also have a couple small wooden table-top easels.
