A standard three-seat sofa is about 180–230 cm (71–90 in) wide, 85–95 cm (33–37 in) deep and 75–90 cm (30–35 in) tall. Two-seat loveseats span 140–180 cm (55–71 in); four-seaters reach 230–300 cm (90–118 in).
Sofas are specified by overall width × depth × height. Width grows with seat count; depth and height stay fairly constant.

A spec table only helps if the buyer reads it. Many don't — shoppers routinely try to judge a product's size straight from the images, and wrong size or fit is the most-cited reason things get returned. The fix is to mark the real dimensions on the photo itself, where the buyer is already looking.
SizeMarker snaps dimension lines to the sofa's edges and exports at Amazon or Alibaba size, so the measurement is accurate and legible — not a guess typed over the picture. That answers the size question up front and cuts pre-sale questions and size-driven returns.
