There are no specific rules on what size a shade should be but here are some tips as an average guide.

​Choosing the right size shade can be confusing, trust your instincts and enjoy the process!

​​

Height ratio: shade height should be roughly 2/3 of the lamp base's height (from table to bulb holder).

Width ratio: the shade's base diameter should be wider than the lampbase's widest part 

Bulb hiding: the shade should cover the bulb & hardware to prevent glare (especially when seated). 

 

General size guideline for table lamps

• Small table lamp base = 8" or 10" shade

• Medium table lamp base (e.g. bedside table or side table) = 10" or 12" shade.

• Large table base (large lamp or floor lamp & pendants) = 12" or 14". 

 

Tips for a perfect fit

Cut a paper circle to your shade's diameter and height and hold it against the base

When in doubt always size up: A larger shade always looks better than one that is too small​
