The height of a table lamp shade should be approximately the height of the base to bottom of socket x 60 up to 70. And when you re considering width don t forget location.
The widest part of your shade should be at least a half inch wider than the widest part of your base on each side. Top denotes the diameter or width if measuring a square lamp shade of the top of the lamp shade. The width of the lamp shade is equal to the height of the base of the lamp. Bottom denotes the diameter or width of the bottom of the lamp shade.
For a round base measure straight across. If you are happy with the size of the shade you are replacing just measure the old one with a ruler or retractable tape measure. If your shade has a square shape measure one side of the square from corner to corner for the proper measurement. Lamp shade dimensions are typically measured as top x bottom x slant.
The slant is the length of the side of the lamp shade. Measure diagonally for a square base. There are three main rules that you need to know when it comes to measuring your lamp shade. The height of a floor lamp shade should be approximately the height of the base x 30 to 40.
