HDB lift door opening is the real limit at ~90cm wide x 209cm tall for furniture delivery today. Standard HDB door measures ~91.5x213cm, but the corridor turn or internal doorway is usually the limiting point. Leave a 2–5cm buffer to avoid getting stuck during the move-in process or when carrying the frame.
Super Single bed frames measure 107x190cm, fitting most HDB master bedrooms comfortably without feeling too large. Buyers usually leave around 60cm clearance on the exit side for easy movement and cleaning access. This size works well where standard single beds feel cramped but queen sizes dominate the available floor space in smaller units.
