Here are some general size recommendations: If your lamp is harp style, we recommend measuring the height of your harp to help us suggest the best lampshade size. 1. If your harp is under 7 inches, we suggest our M-size lampshade, as its height is sufficient to fully cover the harp's metal frame. 2. If your harp is between 7-9 inches, our Large-size lampshade is the best fit, as it's designed for this range. 3. If your harp is over 10 inches, you may need a larger lampshade, which we currently do not have in stock. in this case, we usually recommend switching to a shorter harp or removing the harp entirely to find a better match.
