HDB lift door opening is the real limit at 90cm wide x 209cm tall. Standard HDB doors measure roughly 91.5cm wide x 213cm tall. The lift door, corridor turn, or internal doorway is usually the limiting point. Leave a 2–5cm buffer to ensure successful delivery into the unit.
Rubberwood and plywood frames generally outlast cheaper particleboard options in local conditions. Solid wood handles humidity better without warping as quickly as engineered wood. Budget-friendly options often mix materials, so check the base construction carefully before purchase. This durability matters most for long-term use in BTO flats.
Standard Queen dimensions measure 152x190cm and suit most HDB master bedrooms well. Leave about 60cm clearance on the exit side for easy movement. Single beds measure 91x190cm while Super Singles are 107x190cm wide. Accurate measurements prevent buying frames that block walkways in compact rooms effectively.
