Recognized as America's oldest and most prolific wallpaper manufacturer, York Wallcoverings continues to produce from its historic 1895 location in the heart of Pennsylvania's Susquehanna Valley. The factory still operates its rare, turn-of-the-century presses to this day while utilizing modern, digitally innovative processes to create wallpaper designs both distinct in quality and craftsmanship. To calculate the square footage of your space, we recommend combining the width of each wall, then multiplying this number by your ceiling height. Next, divide this number by the square footage of a single roll of wallpaper to determine the number of rolls required. Always round up to account for pattern repeat and variation.
