Queen size measures 152x190cm and fits most HDB master bedrooms without overcrowding. Leave roughly 60cm clearance on the exit side for comfortable movement around the frame. Super Single at 107x190cm works well in smaller rooms like HDB common bedrooms. Selecting the right dimensions ensures the bed doesn't dominate the available floor area.
HDB lift door opening is the real limit at roughly 90cm wide by 209cm tall. Standard HDB door measures 91.5x213cm but the corridor turn often causes issues. Leave a 2–5cm buffer when planning the delivery route for bulky furniture. Check the path carefully to avoid getting stuck on the way to the unit.
