Lampshade Size Guide

Step 1: Start with the Basics

Every great lampshade selection begins with understanding your lamp’s components. Learn how harps, finials, and washers work together and discover easy adapter solutions for nearly any lamp. Even vintage or unusual fittings can usually be customized for your needs—if you're stumped, a visit to your local lamp shop can make all the difference.


Step 2: Learn the Proportions

Aim for harmony! The classic sizing rule is to choose a shade about double the width of your lamp base and one-third the base's height. Use these time-tested proportions to guide your selection, but don't forget: trust your eye if something just looks right. Borrow a shade from another lamp for reference or experiment with swapping sizes to find what suits your space best.


Step 3: Master the Measure

Precision creates elegance. Lampshade sizes are defined by their bottom diameter (in even numbers) and measured using the convention Top x Bottom x Slant. Accurate measurement ensures your shade works perfectly with table lamps, buffet lamps, or floor lamps. Choosing appropriately sized shades will help set a balanced, beautiful look throughout your home.


Extra Credit: Finesse the Fit

The final step is all about details. Tweaking harp height can completely change how a shade sits and looks; harps have stamped sizes for easy swaps. If you’re working with vintage lamps, professionals can help adjust or replace hardware for a flawless fit. These finishing touches guarantee both comfort and style.
