Frequently Asked Questions

How do I calculate square meters?

Multiply length times width in meters. For irregular shapes, divide the area into rectangles, triangles, or circles, calculate each separately, and add the results.

How much living space do I need per person?

The German average is about 47 square meters per person. Guidelines suggest a minimum of 13 square meters per person. Family homes typically range from 120-180 square meters.

What is the Square Meter Calculator?

The square metre calculator computes the area from length and width and converts between area units.

How does the Square Meter Calculator work?

Enter length and width. For irregular areas you can break them into sub-areas. The calculator adds the sub-areas and shows the result in sqm and other units.

Key Data and Facts

1 m squared = 10,000 cm squared = 0.0001 ha. 1 ha = 10,000 m squared. 1 are = 100 m squared. Living area per WoFlV: balconies 25-50%, areas under 1 m ceiling not counted.

Step-by-Step Guide

How to calculate Quadratmeter step by step: 1. Rechteckige Flaeche: Messen Sie Laenge und Breite in Metern. m2 = Laenge x Breite. 2. Unregelmaessige Raeume: Teilen Sie die Flaeche in Rechtecke und Dreiecke auf. calculate Sie jede Teilflaeche einzeln und addieren Sie die Ergebnisse. 3. Wohnflaeche nach WoFlV: Vollstaendig anrechenbar: Raeume mit Deckenhoehe ueber 2 m. Zu 50 %: Raeume mit Deckenhoehe 1-2 m (Dachschraegen). Nicht anrechenbar: unter 1 m Deckenhoehe. Balkone/Terrassen: 25 % (in der Regel). 4. Einheiten umrechnen: 1 m2 = 10.000 cm2. 1 ha = 10.000 m2. 1 Ar = 100 m2. 1 km2 = 1.000.000 m2. 5. Materialberechnung: Fliesen/Parkett: Flaeche + 5-10 % Verschnitt. Farbe: ca. 100-150 ml/m2 pro Anstrich. Tapete: Wandflaeche = Umfang x Raumhoehe minus Fenster/Tueren.

Calculation Example

L-foermiger Raum: Teil 1: 5 x 4 = 20 m2. Teil 2: 3 x 2,5 = 7,5 m2. Gesamtflaeche: 27,5 m2. Laminat mit 8 % Verschnitt: 27,5 x 1,08 = 29,7 m2 bestellen.
