How is the price of glass and mirrors calculated?
The price of custom glass and mirrors is based on the surface area in m² plus any processing or options you choose. A minimum chargeable surface area per piece often applies, because glass is cut from large sheets and every piece involves fixed costs. The configurator shows the price straight away, including VAT.
Base price: price per m²
The base price is calculated by multiplying the width × height and converting the result into square metres (m²).
- Width (mm) ÷ 1000 = metres
- Height (mm) ÷ 1000 = metres
- Surface area = width (m) × height (m)
Example: 600 × 800 mm = 0.6 × 0.8 = 0.48 m²
Options that affect the price
On top of the surface area, the price depends on the options and processing you select, for example:
- edge finishing (seamed or polished edges)
- drilled holes or cut-outs
- safety glass options (for example tempered or laminated glass)
- special coatings or finishes
On the product page, the price updates as soon as you select an option.
Minimum chargeable surface area per piece
For many types of glass and mirrors, a minimum chargeable surface area per piece applies. If your piece is smaller than that minimum, you pay for the minimum area.
This is common in custom glass production, because some costs are the same whatever the size of the piece, such as cutting loss from large sheets, production setup and handling.
Example (for illustration only): suppose the minimum chargeable area is 0.50 m² per piece.
- You order 300 × 400 mm → 0.3 × 0.4 = 0.12 m² → you pay for 0.50 m² (the minimum).
- You order 800 × 900 mm → 0.8 × 0.9 = 0.72 m² → you pay for 0.72 m² (the actual size).
The minimum applies per piece
The minimum chargeable surface area applies to each individual piece, not to the whole order. If you order several small pieces, the minimum can apply to each piece separately.
Where can I find the minimum surface area?
The minimum differs per type of glass or mirror. The product page and the configurator include it in the price automatically.

In short: your price is based on the calculated m² (or the minimum m² where it applies) plus any processing or options you select.
