What lamp shade size do I need?
Lamp shade size guide
We know that picking the right size shade can feel a trifle confusing, especially if you layer in the advice on ratios between lamp base and shade diameter. It need not be so complicated though because really, like with most things in interiors, there are no rights or wrongs. All there is, is guidance, which is what you’ll find right here.
General rule to choosing the right size lamp shade
As a general rule of thumb, the most pleasing proportions are picking a lampshade that’s base is two-thirds the size of your lamp base. Use that as a starter for ten, but we find it most helpful to find a lampshade elsewhere in your home – if you can – that’s a similar size to what you have in mind and test it out. Or try fashioning one out of paper and popping it onto your lighting fixture to give you peace of mind before you part with your pennies.
