Kaip apskaičiuoti kvadratūrą?

Kvadratūra apskaičiuojama dauginant patalpos ilgį iš pločio. Pavyzdžiui, 6 m × 4 m = 24 m². L formos patalpos kvadratūra — du stačiakampiai, kurių plotai sudedami.

Kaip apskaičiuoti grindų kvadratūrą?

Grindų kvadratūra skaičiuojama taip pat kaip patalpos kvadratūra — ilgis × plotis. Skirtumas tik tas, kad reikia atimti vietas, kuriose grindys nebus klojamos: virtuvės salos, židinio pagrindas, įmontuoti baldai.

Kas yra kvadratūros skaičiavimas ir kodėl jis svarbus?

Kvadratūros skaičiavimas — patalpos paviršiaus ploto nustatymas kvadratiniais metrais. Tai pagrindinis žingsnis užsakant grindų dangą: parketlentės, vinilinės grindys ir plytelės kainuojamos už m².

Kuo kvadratūros skaičiuoklė geriau už paprastą skaičiavimą?

Skaičiuoklė automatiškai prideda atsargą pagal pasirinktą klojimo modelį, apskaičiuoja grindjuosčių kiekį pagal perimetrą ir įvertina durų plotus.

Kiek atsargos pridėti prie kvadratūros?

Tiesinis klojimas — 7–10 %, diagonalinis (45°) — 10–13 %, eglutės raštas — 12–15 %. Sudėtinga geometrija — iki 15 %.

How to calculate the area — step by step

To work out how to calculate the area, all it takes is three simple steps. The same principle applies to engineered wood, vinyl flooring, laminate and ceramic tiles — any floor covering measured in square metres.

1. The basic formula

The area of a rectangular room is calculated by multiplying its length by its width:

Area (m²) = Length × Width

Example: 6,5 m × 4,2 m = 27,3 m². For an L-shaped room, split it into two rectangles — calculate each area separately and add them together.

2. Add a wastage allowance for your laying pattern

The exact area is not the whole story — you also need to allow for cuts and offcuts:

Straight laying — add 7–10% for wastage.
Diagonal (45°) — add 10–13%.
Herringbone and chevron patterns — add 12–15%.
Complex layouts (many corners, corridors) — up to 15%.

3. Round up to full packs

Engineered wood boards are sold in full packs (typically 2,5–3,2 m² per pack) — an order cannot be split down the middle. Always round up to the nearest full pack. We recommend keeping one unopened pack for the future — natural wood varies between batches.

Frequently asked questions

How do I calculate the area?

The area is calculated by multiplying the room's length by its width. For example, 6 m × 4 m = 24 m². For an L-shaped room, treat it as two rectangles and add their areas together. Our floor area calculator does this automatically.

How do I calculate the floor area?

The floor area is calculated in the same way as the room area — length × width. The only difference is that you need to subtract the areas where flooring will not be laid: kitchen islands, a fireplace hearth, built-in furniture. Our calculator has a dedicated "Deductions (m²)" field for this.

What is floor area calculation and why does it matter?

Area calculation means working out a room's surface area in square metres (m²). It is the key step when ordering flooring: engineered wood, vinyl flooring and tiles are priced per m². An accurate area calculation with a wastage allowance (10–15%) helps you avoid both under-ordering (which stalls the build) and over-ordering (wasted money).

How is the area calculator better than working it out by hand?

Our floor area calculator automatically adds a wastage allowance based on the chosen laying pattern (straight, diagonal, herringbone), calculates the amount of skirting board from the perimeter and accounts for door openings. When calculating by hand it is easy to overlook one of these — and the result is an order that comes up short.

How much wastage should I add to the area?

The allowance depends on the laying pattern: straight — 7–10%, diagonal (45°) — 10–13%, herringbone or chevron — 12–15%. Complex layouts (many corners, corridors) — up to 15%. The calculator adds the allowance automatically based on the chosen pattern.
