How do Japanese shikibuton sizes compare with local bed sizes?

HIMARI is 210 cm long, in 100, 120 or 140 cm widths; SORA is 200 cm long, in 100 or 140 cm widths. Compare both length and width with your floor, platform or bed frame.

Choose by centimeter dimensions rather than local size names. HIMARI is 210 cm long, in 100, 120 and 140 cm widths, and approximately 10 cm thick. SORA is 200 cm long, in 100 and 140 cm widths, and approximately 12 cm thick. Check the sizes offered for your delivery country. Measure the usable support area of your bed or floor and choose sheets by the same dimensions.

Common U.S. bed widths: Twin 97 cm (38 in) · Full 137 cm (54 in) · Queen 152 cm (60 in). Measure your floor, platform, or frame before ordering.

Local mattress sizes vary by country and by maker, so compare the centimetre dimensions with the usable support area of your frame rather than relying on a size name.

Fitting a frame and choosing sheets

If you plan to use a bed frame built for a local mattress size, measure its inside dimensions and make sure the whole shikibuton is supported. Choose sheets and covers by the centimeter dimensions. Custom sizes are not available.
