# Calculation of the number of rolls of wallpaper by room area

We decided to re-paste the wallpaper in the house on our own ?! But do not know how many rolls you will need to purchase ?! No problem! Our calculator will solve this problem for you. You only need to measure - the width and length of the room, the height of the ceilings, the width and height of windows and doors, as well as determine what kind of wallpaper you will buy with what width and length of the roll. When you enter data in the rows and below, click the calculate button. And you will have the required number of rolls specifically for your parameters.

You can enter not only integers, but also decimal fractions, but instead of a comma *put a point *(eg** 15.3**).
