How to Measure a Lampshade for a Table Lamp?

In case you don’t have a lampshade before or don’t care what size the existing one has, this section will help you. Here we will discuss how you can measure a lampshade for your table lamp.

There are two things in particular that you need to keep in view when buying a table lamp shade. That is height and width. Below we have discussed both of them in detail, so you know how things work.

How to Measure a Table Lamp



As a general rule of thumb, the height of your lampshade should be half of the height of your lamp’s height. This height is considered from the base of the lamp to the bottom of the shade – bulb rod is not included in it.

Let’s say a table lamp has a height of 20 inches. The shade you are about to buy should be 10 inches in height. That’s how it will match the vibe of your lamp.


After you are done with the height section, consider the width of your lampshade. Remember that the shades are always wider than the lamp base. It should be double that of your base. If your base is 8 inches wide, have a lampshade with 16 inches diameter.

All in All…

Considering the measurements above, it’s safe to say that a shade should be wide than your lamp base and half the height. And for a 20 inches heightened lamp, the shade should be 10 inches tall, while the 8 inches wide lamp base should have 16 inches lampshade from the bottom.

How to Measure a Lampshade for a Floor Lamp?

Floor lamps are different than table lamps. They are in direct contact with your ground and are placed in multiple nooks of your home. The function and intent of these lamps also differ from table lamps.

Just like that, the measurements of their shade are also distinctive. You’ll consider the height and width for them too, but the result would be fairly different. So, check out this section if you are interested in buying a floor lamp shade.

How to measure a floor lamp


Floor lamps are tall than table lamps. To make a perfect lampshade to sit on them, start by measuring its height. Measure from the base to the bottom of the bulb holder. Note this reading and divide it by 4. The result of this calculation will be the height of your lampshade.

Assuming your floor lamp is 60 inches high. Dividing 60 by 4 turns out 15. That means your shade should be 15 inches to compliment the height of the lamp and its style.


The width or diameter – you name it – of your lampshade should be more than the base of your lamp. Its bottom should pass the base to give the lamp an excellent look. Generally speaking, a lampshade of 18 inches in width is considered ideal for most floor lamps.

All in All…

Keeping in view the above statements, it’s apparent that the lampshade of your floor lamp should be wide than the base and ¼ the height. For a 60 inches lamp, 15 inches tall shade is fair with 18 inches diameter from the bottom.
