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 bed frame'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.

A queen mattress is 60 × 80 in (152 × 203 cm). The frame that holds it typically measures 62–65 in wide by 82–85 in long externally — 2–5 in bigger than the mattress on each dimension (Purple).
Most bed frames add 2 to 5 in (5–13 cm) to both width and length, giving about 1–2.5 in of clearance per side for tucking sheets (Purple; Amerisleep).
A UK King is 150 × 200 cm (5'0" × 6'6"), noticeably narrower than a US King at 76 × 80 in (193 × 203 cm). UK Super King (180 × 200 cm) is closer in width but still about 3 in shorter (Dreams.co.uk; Sleep Foundation).
Headboards are sized in three tiers measured from the top of the mattress: 14 in (36 cm) for Twin, 28 in (71 cm) for Full and Queen, and 58 in (147 cm) for King and California King (Amerisleep; Casper).
Low-profile frames run 7–11 in (18–28 cm) floor-to-top, standard platforms 10–14 in (25–36 cm), and storage/elevated frames 14–18 in (36–46 cm). Total bed height with mattress averages about 24–25 in (61–64 cm) (Purple; NapLab).
