Door Opening Measurement Guidelines

To ensure a perfect fit for custom-made aluminum alloy doors and windows, precise measurements are essential. Follow these steps carefully:

  • 1Width Measurement: Measure at three points: top (Width 1), middle (Width 2), and bottom (Width 3). Take the smallest value of the three. Subtract 3–5 mm (depending on wall flatness) from the minimum to get the final width.
  • 2Height Measurement: Measure at three points: left (Height 1), center (Height 2), and right (Height 3). Take the smallest value of the three. Subtract 3–5 mm (depending on wall flatness) from the minimum to get the final height.
  • 3Wall Thickness Measurement: Measure at three points across the depth (Thickness 1, 2, and 3). Take the largest value of the three. Subtract 2–3 mm (depending on wall conditions) to determine the final thickness.
⚠️ Note: Due to variations in civil construction, wall openings may not be perfectly straight or uniform. That’s why multi-point measurement and reasonable adjustment are crucial to ensure both installation accuracy and aesthetic appearance.
