We are happy to help you in choosing a mirror.
Take a photo of the wall where the mirror is to go and the opposite wall so we can get an idea of what the mirror will be reflecting.
Take measurements of the space and come see us in store, We are more than happy to assist with size and style.
Also bring in measurement of what the mirror is hanging over, side board, canity, mantle , bed etc…..
You can always cut out some paper or use Blue Tack in corners to see how it will fill then space.
Don’t be scared of size, a mirror can never be too big but it can be too small. an area of wall space around the mirror and above the mirror, but fill the majority of the space available for the best effect.
