Here's a quick guide to help you choose:
64mm — the narrowest option, closest in character to original plantation shutters found in period homes. Suits smaller windows and Victorian or Edwardian properties where a traditional fine-slatted appearance is the priority.
76mm — the most popular louvre size in the UK market.
89mm — suits large windows and contemporary interiors where a cleaner, more minimal look matters more. Particularly good for bay windows, bifold doors and large modern openings.
