Shutters come with louvres in different sizes for good reason.
One reason is to let in more, or less light.
The other is to match the proportions of the window or the room.
Smaller windows suit narrower louvres, larger windows suit wider ones.
Generally, the wider apart the louvres are when they are opened, the more light and view they let in
But there is always personal taste to take into account so don't panic if you prefer different.
The most popular slat / louvre size we sell is 63 / 64 mm. This size gives an overall balanced look to most domestic windows and gives good privacy vs light control.
