This lampshade is not the U.S. standard UNO ring size and doesn't fit a standard socket. The website description doesn't list ring size, only that it's UNO style attachment which should be 1 and 7/16 inch. This lamp’s ring diameter is 1 and 5/16 making it unusable.

To small for my mother's floor lamp

Love this!! Perfect size... amazing buy. I had been looking for like 2 months and who knew it was THAT involved to buy a lamp shade. Done and done!

Beautiful. Fit perfectly on lamps I had purchased that had super cheap shades. Transformed them!

This is small and simple. Love the color, but it gets a little lopsided easily on my lamp… maybe I just need to tighten things but it’s nice. Nothing special and definitely not “expensive looking,” but gets the job done if you’re wanting to easily change up the look of a lamp or the shade it oldoutdated. Neat
