uPVC Window Standard Sizes vs Made-to-Measure

uPVC Window Standard Sizes vs Made-to-Measure — here's a clear, practical explanation.

Standard sizes versus made-to-measure

While there are common window sizes, real openings — especially in older homes — are rarely exactly standard. That's why uPVC windows are usually made to measure.

What to know

Look for this

  • Common sizes exist as a reference
  • Real openings are rarely exactly standard
  • Made-to-measure ensures a proper fit
  • Older homes especially vary
  • Built to your actual opening

Why it matters for your windows

Rather than force a standard size and fill gaps, we measure your actual openings and build to them — the only way to a clean, sealed fit.
