Is there a minimum plugin editor size for all/most known hosts?

I’m developing a utility plugin which doesn’t need a lot of UI elements.
However, I just noticed that its UI is too small for e.g. Pro Tools where you get pillarboxes on the sides which looks rather odd.

Is there some kind of minimum UI size that I can design for to make sure it’s displayed correctly on all or most known hosts?


Try Reaper for ugly small plugins … probably the worst.

Thanks Jim. I think I’m rather looking for the opposite.
Pro Tools seems to require the plugin to be at least about 450 pixels wide.
Otherwise it will add pillarboxes.

I was wondering if there are hosts requiring even more minimum width before adding pillarboxes.
