What size lampshade do I need?

Choosing the right size lampshade makes a huge difference to the look and feel of your lamp. Go too small and it can look a bit awkward, like a hat that’s shrunk in the wash. Fortunately, it’s easy to get it right.

Here are a few quick rules of thumb to help:

  • As a general guide, your lampshade should be around two-thirds the height of your lamp base.
  • The diameter of the shade should usually be wider than the base – at least matching it, ideally a touch more.
  • If in doubt, it’s usually better to size up – a shade that’s slightly too big often looks far better than one that’s too mean and poky.
  • For table lamps, aim for balance: you want the bulb hidden, the lamp stable, and the proportions pleasing.
  • For floor lamps, go for depth and drama – larger shades suit their scale.
  • And for smaller rooms, choose a more compact shade to keep the space feeling airy.

Quick tips:

  • If your shade wobbles or shows the bulb, it’s probably too small.
  • If it looks top-heavy or casts shadows too low, it might be too big – but it’s still usually the lesser evil!
  • Still unsure? Try paper templates or measure your current shade for a starting point.
