Metric Size Internal Doors | Perfect UK Fit

Metric Internal Doors – Built for UK Specifications

Looking for internal doors that meet modern metric measurements instead of outdated imperial sizes? At Doorphoria, our metric size doors are manufactured to match UK-standard metric door frames — making them ideal for newer homes, self-builds, and refurbishments where exact sizing matters.

Metric doors are slightly wider and taller than traditional imperial-sized doors and typically come in heights like 2040mm rather than 1981mm. Whether you’re replacing existing doors or starting from scratch, we stock a wide range of styles, finishes, and fire-rated options in metric dimensions.

Why Choose Metric Size Internal Doors?

• ✅ Made for UK Frame Sizes – Perfect for properties built to metric construction standards (common in post-1970s builds).

• ✅ Precise Sizing – Typically available in 2040mm heights, with 626mm, 726mm, and 826mm widths.

• ✅ No Need to Cut Down or Alter – Save time on site and maintain door structure with doors that fit first time.

• ✅ Available in All Styles – Choose from shaker, glazed, flush, oak, black, white primed and more.

• ✅ Fire Rated Metric Doors – FD30 options available for compliance with safety regulations.

These doors are especially useful when you’re matching new doors to modern door linings or frames without needing to trim or risk misfitting.
