Rules that make the choice easier
Match the regional audience
Use theater for ordinary US copy and theatre for ordinary UK copy unless a required style says otherwise.
Preserve official names
A venue, company, course, or festival controls its own spelling. Copy that name exactly.
Do not invent a strict art-versus-building rule
Some US writers prefer theatre for the art and theater for the building, but this is not a universal English distinction.
Common mistakes to avoid
- Do not claim the spellings always separate art from buildings.
- Do not change the spelling in an official venue name.
