Home decor, explained by the numbers
Most decorating advice stops at inspiration. These guides carry on to the part that decides whether a room works: the fiber, the finish, the lumens, the inches and the actual bill.
Home Craft Blog is an editorial publication. We do not run a design studio and we do not photograph client projects. What we do is read the specification sheets, compare what manufacturers publish, check the conventions against their sources, and write up what a person needs to know before spending money. Where a number appears in these guides, it comes from a document we can point you to.
Every guide is written to be used while you are standing in the room with a tape measure, not while you are scrolling. If something here is wrong or out of date, tell us and we will correct it.
