I purchased these blinds to fit inside a 30 inch window. From the description it seemed that I would be ok with ordering a 30 inch blind since it said they could be used for inside or outside mount. The blinds arrived and were too long!! Only by about 1/16 of an inch but enough so that they wouldn't fit in the window. I was able to mount them by bending the top bracket but it wasn't easy. I was just in a rush to get them up and didn't want to deal with sending them back. Be careful when ordering!!
