The official badminton court size is 13.40 m long and 6.10 m wide for doubles, narrowing to 5.18 m for singles, with the net at 1.55 m. This guide gives every measurement that matters — court length and width, net height, service lines and tramlines — explains the singles-versus-doubles boundary switch that confuses everyone, and shows how much space you actually need to fit a court at home or in a hall, all with a clear labelled diagram.
Badminton net height is 1.524 m at the centre and 1.55 m at the posts — most club nets hang too low because players measure the posts and ignore the sag in the middle. This guide covers official BWF net dimensions, post placement rules, court line widths, and a quick setup checklist to make sure your court is regulation before you play.
