Every room raises the same handful of sizing questions: what size rug, how long the curtains, how high the TV, how much paint. These free tools answer them from your own measurements, using the rules interior designers use, and turn the answer into a size you can actually buy. Nothing to sign up for, nothing to install. They work on your phone while you stand in the room with a tape measure.
How these tools work
Each calculator starts from a published design guideline, like 18″ of bare floor between a rug and the walls, or curtains hung high and wide. It then snaps the result to the standard sizes sold in stores, so you are never told to buy a rug or a curtain panel that does not exist. Every page explains the rule it uses, with a chart and worked examples, so you can check the answer yourself.
Every result has its own link: Copy link saves the numbers you entered, so you can send a size to someone or come back to it in the shop.
Put a calculator on your own site
Every calculator has an Embed this calculator button. It gives you a short piece of code to paste into a page on your blog or website. The calculator works there exactly as it does here, free, with a credit line linking back to Dreamy Home Style.
Plan the whole room
A calculator answers one question at a time. To see how everything fits together, draw the room in the free 2D room planner and try the rug, the sofa and the bed at their real sizes.
