Before you go to the home improvement store to purchase building materials, use our calculators to determine how much you need. Whether you're painting, installing new flooring or drywall, buying lumber or tile, knowing exactly how much you need safeguards against buying too much and wasting money, and buying too little and having to return to the store to get more. Precision counts when measuring for the materials you'll be using in your projects. When your measurements are accurate, your home improvement or remodeling project will go more smoothly and the results will be fantastic. Different materials -- from paint to concrete, baseboards, wallpaper, pavers, and more -- require different types of measurements. Use our material calculators to get an accurate estimate, and follow our tips for measuring. Build upon the basic principle of "measure twice, cut once" and learn how to make precise measurements for all your projects. Plus, calculate the square footage of different rooms and spaces to get an idea of how big it is, which will help you when shopping for furniture, window treatments, area rugs, and more.
