SidingCalc is a siding calculator that works out squares, boxes or planks of siding and the corner posts, J-channel and starter strip for a house — with no account.
It was built to be fast and private. There are no accounts and no uploads; every calculation happens in your browser. The site may be supported by unobtrusive advertising, which never appears inside the tool itself.
