Browse patterns on manufacturer websites, then order samples, rolls, and swatch books to feel the paper’s texture and test its color in your rooms.
Some makers sell directly to the public online. Others refer you to third-party online boutiques, such as Walnut Wallpaper;
interior-design showrooms; or paint shops, such as Sherwin-Williams.
Big-box stores, like Lowe's and The Home Depot, sell select papers in stores but put the lion's share of their offerings online. Target sells only via its website.
Most sites provide interactive software that allows you to visualize how a paper will look on your walls and to calculate how much you'll need. Wallpaper rolls vary in width and length, so you have to find the square footage of each roll in order to compare prices and buy the right amount.
