Made to measure Roller Blinds, Vertical Blinds, Venetian and Roman Blinds all at competitive prices take a look at our huge range unique to Webstyle Blinds. The best way to measure your window blinds correctly is to have a metal tape measure to hand (you can buy this in extras if you do not have one). Always start by measuring the WIDTH first followed by the DROP. Take a look at your window and decide were you are wanting the blinds or shutters to hang. Once you have decided were the blinds are going to go, check the window to see if there are any obstructions. Make sure you have a pen and paper to hand then start measuring the WIDTH in three places top-middle-bottom, write the smallest measurements down. Once you have measured the WIDTH then measuring the DROP, you have already decided were the blind is going to hang. So start measuring from the top of the window to the bottom of the window left-middle-right then write down the smallest measurement for verticals, roman's, shutters & panel blinds.
