A room 4 m long and 3 m wide has an area of 4 \u00d7 3 = 12 m\u00b2.<\/p>\n\n\n\n<div id=\"sf-quadratmeter-tool\" style=\"min-height:640px;\"><\/div>\n<script src=\"https:\/\/tools.schwiizerfranke.com\/quadratmeter-rechner\/embed.js\" defer><\/script>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The square metre calculator, also known as a qm calculator or m\u00b2 calculator, calculates the area of individual rooms, entire flats, lofts and plots of land, and also calculates costs per m\u00b2 and converts between all units.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the online square metre calculator, you can easily work out areas, floor spaces or even land prices. Even converting square metres into square centimetres, hectares or square kilometres is no problem. As an area calculator, it also works for triangles, circles and L-shaped rooms. You\u2019ll find all the relevant formulas in this article.<\/p>\n\n\n\n\n<div class=\"wp-block-group sf-keypoints is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"sf-keypoints__t wp-block-paragraph\">Key points at a glance<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Formula:<\/strong> Length \u00d7 width = area in square metres (m\u00b2).<\/li>\n\n\n\n<li><strong>3 \u00d7 3 metres<\/strong> is 9 m\u00b2; 4 \u00d7 4 metres is 16 m\u00b2.<\/li>\n\n\n\n<li><strong>Irregular rooms<\/strong> Divide it into rectangles and add up the areas.<\/li>\n\n\n\n<li><strong>Roof pitch:<\/strong> In Switzerland, only the area with a ceiling height of 1.50 m or more is usually counted as living space.<\/li>\n\n\n\n<li><strong>Convert:<\/strong> 1 m\u00b2 = 10,000 cm\u00b2, 1 hectare = 10,000 m\u00b2, 1 Juchart = 3,600 m\u00b2.<\/li>\n<\/ul>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Calculate floor space, areas and plots of land using the square metre calculator<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One square metre is the area of a square with sides measuring 1 m. The same formula applies to any rectangular area, whether it be a room, a floor, a terrace or a plot of land:<\/p>\n\n\n\n<div class=\"wp-block-group sf-tip is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Area in m\u00b2<\/strong> = Length in m \u00d7 Width in m<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example:<\/strong> How big is a plot of land that is 30 m long and 15 m wide? 30 m \u00d7 15 m = 450 m\u00b2. You can work out the area in square metres by multiplying the length by the width.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short: 2\u00d72 metres is 4 square metres; 3\u00d73 metres is 9 square metres.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The only important thing is that both measurements are in the same unit. If you\u2019re measuring in centimetres, you first convert to metres: 350 cm is 3.5 m. The calculator above does this for you if you switch to \u00abcentimetres\u00bb.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Mass<\/th><th>Area<\/th><\/tr><\/thead><tbody><tr><td>2 \u00d7 2 metres<\/td><td>4 m\u00b2<\/td><\/tr><tr><td>3 \u00d7 3 metres<\/td><td>9 m\u00b2<\/td><\/tr><tr><td>4 \u00d7 3 metres<\/td><td>12 m\u00b2<\/td><\/tr><tr><td>4 \u00d7 4 metres<\/td><td>16 m\u00b2<\/td><\/tr><tr><td>5 \u00d7 5 metres<\/td><td>25 m\u00b2<\/td><\/tr><tr><td>10 \u00d7 10 metres<\/td><td>100 m\u00b2 (1 are)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A square metre is written as m\u00b2, and is often also written as qm or m2. It always means the same thing, whether you want to calculate qm or m\u00b2.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Calculating the square metres for an entire flat<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For a flat, measure each room individually and add the areas together. Measure across the floor from wall to wall, excluding door thresholds. If a room is L-shaped, calculate the area of the large rectangle and subtract the missing corner. A living room measuring 6.5 \u00d7 5 m, with a corner of 2.5 \u00d7 2 m missing, has an area of 32.5 m\u00b2 \u2212 5 m\u00b2 = 27.5 m\u00b2.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To do this, simply add more rooms in the calculator. It will show you the area of each room and the total.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How big are 30 or 500 square metres?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Numbers alone don\u2019t tell the whole story. 30 m\u00b2 is a square measuring roughly 5.5 \u00d7 5.5 m \u2013 the same as 2.4 car parking spaces. 500 m\u00b2 is a square measuring roughly 22 \u00d7 22 m \u2013 just under two tennis courts. The calculator shows you a comparison like this for each area in the \u00abConvert\u00bb tab.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Triangle, circle and trapezium<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Triangle:<\/strong> Base \u00d7 height \u00f7 2. A triangle with a base of 4 m and a height of 3 m has an area of 6 m\u00b2.<\/li>\n\n\n\n<li><strong>District:<\/strong> \u03c0 \u00d7 diameter\u00b2 \u00f7 4. A round flowerbed with a diameter of 2.5 m has an area of approximately 4.91 m\u00b2.<\/li>\n\n\n\n<li><strong>Trapezium:<\/strong> (long side + short side) \u00f7 2 \u00d7 height. With dimensions of 5 m, 3 m and a height of 3 m, that makes 12 m\u00b2.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Calculating living space with sloping ceilings<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the attic, the floor area is larger than the living area. You cannot stand everywhere under a sloping ceiling, so this part is not counted, or only counted in part. The rule that applies depends on the country.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th><\/th><th>Switzerland<\/th><th>Germany<\/th><\/tr><\/thead><tbody><tr><td>Basis<\/td><td>Housing subsidy schemes in practice, e.g. the Canton of Zurich<\/td><td><a href=\"https:\/\/www.gesetze-im-internet.de\/woflv\/__4.html\" target=\"_blank\" rel=\"noopener\">Housing Area Regulation (WoFlV) Section 4<\/a><\/td><\/tr><tr><td>Counts fully<\/td><td>from a ceiling height of 1.50 m<\/td><td>for rooms with a ceiling height of 2 metres or more<\/td><\/tr><tr><td>Counts as half<\/td><td>nothing<\/td><td>1 to just under 2 m<\/td><\/tr><tr><td>Doesn't count<\/td><td>under 1.50 m<\/td><td>less than 1 m<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example:<\/strong> An attic room is 5 m long and 4 m wide, giving a floor area of 20 m\u00b2. The sloping ceiling starts at the wall at a height of 0.8 m and rises at an angle of 40 degrees. The distance to the ceiling, which is 1.50 m high, is just over 80 cm. Consequently, only 15.83 m\u00b2 counts as living space; around 4 m\u00b2 is excluded.<\/p>\n\n\n\n<div class=\"wp-block-group sf-anchor is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\">If a straight sloping wall begins at a wall height of less than 1 metre, the Swiss and German rules yield exactly the same living area. It is only when the walls are higher that the German rule results in a lower figure.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">That sounds like a coincidence, but it\u2019s actually geometry: On a straight sloping surface, the half-count between 1 and 2 metres corresponds exactly to the strip between 1.50 and 2 metres. If, on the other hand, the wall is 1.20 metres high, the Swiss rule in the example gives 18.21 m\u00b2, whilst the German rule gives only 17.62 m\u00b2.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, what is set out in the tenancy or purchase agreement is binding; in Switzerland, this is often calculated in accordance with the SIA 416 standard. You should therefore check property adverts to see whether the floor area or the living area is stated.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Square meter calculator convert area to side length<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you know the area and one side length, you can work out the missing side as follows:<\/p>\n\n\n\n<div class=\"wp-block-group sf-tip is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Page a<\/strong> = Area \u00f7 side b<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example:<\/strong> A plot of land measures 200 m\u00b2; one side is 45 m long. The other side is 200 m\u00b2 \u00f7 45 m = 4.44 m.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People often ask how many \u00abmetres\u00bb 30 square metres is. You can\u2019t convert this directly, because a square metre is an area and a metre is a length. However, you can work out how long the side of a square with that area would be: this is the square root of the area. 30 m\u00b2 corresponds to a square measuring approximately 5.48 \u00d7 5.48 m, whilst 1 m\u00b2 corresponds to a square measuring 1 \u00d7 1 m.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Determine prices of land with the square meter calculator<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You can easily work out the price of a plot of land by multiplying its area by the price per square metre. This works in exactly the same way for floors, walls or lawns.<\/p>\n\n\n\n<div class=\"wp-block-group sf-tip is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Costs<\/strong> = Plot area \u00d7 price per square metre<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example:<\/strong> A plot of land measures 600 m\u00b2; the land costs CHF 1,850 per m\u00b2. That works out at 600 \u00d7 CHF 1,850 = CHF 1,110,000.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conversely, if you divide the rent by the floor area, you get the price per m\u00b2. A flat measuring 75 m\u00b2 with a rent of CHF 1,800 costs CHF 24 per m\u00b2 per month, or CHF 288 per m\u00b2 per year. For commercial premises in Switzerland, this annual figure is usually stated in the advert. This allows you to compare offers fairly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When it comes to floor coverings, you should allow for slightly more material than the surface area alone: usually 5 to 10 % for offcuts and a margin, or around 15 % for tiles laid in a diagonal pattern. If you want to know whether you can afford a flat or a house, the <a href=\"https:\/\/www.schwiizerfranke.com\/en\/tragbarkeitsrechner\/\">Affordability calculator<\/a>. The calculator shows whether it\u2019s worth buying rather than renting <a href=\"https:\/\/www.schwiizerfranke.com\/en\/mieten-oder-kaufen\/\">Rent or buy<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Convert QM2 calculator to cm\u00b2, km\u00b2 or hectare<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For areas, the conversion factor increases in proportion to the square. 1 m is 100 cm, but 1 m\u00b2 is 100 \u00d7 100 = 10,000 cm\u00b2. Here are the most important conversions:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Unit<\/th><th>In square metres<\/th><\/tr><\/thead><tbody><tr><td>1 square centimetre (cm\u00b2)<\/td><td>0.0001 m\u00b2<\/td><\/tr><tr><td>1 square decimetre (dm\u00b2)<\/td><td>0.01 m\u00b2<\/td><\/tr><tr><td>1 are (a)<\/td><td>100 m\u00b2<\/td><\/tr><tr><td>1 Juchart (Switzerland)<\/td><td>3,600 m\u00b2<\/td><\/tr><tr><td>1 hectare (ha)<\/td><td>10,000 m\u00b2<\/td><\/tr><tr><td>1 square kilometre (km\u00b2)<\/td><td>1,000,000 m\u00b2<\/td><\/tr><tr><td>1 square foot (sq ft)<\/td><td>0.0929 m\u00b2<\/td><\/tr><tr><td>1 acre<\/td><td>4,046.86 m\u00b2<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li>From square metres to square centimetres: multiply by 10,000.<\/li>\n\n\n\n<li>From square metres to hectares: divided by 10,000.<\/li>\n\n\n\n<li>From square metres to square kilometres: divided by 1,000,000.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In English property adverts, \u2018sqm\u2019 often stands for \u2018square metre\u2019. These are just standard m\u00b2, so you don\u2019t need to convert anything. It\u2019s different with \u2018sq ft\u2019 (square feet): in that case, you divide by around 10.76 to get the figure in m\u00b2.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Juchart is an old Swiss unit of area for land. Originally, it was the area that a team of horses could plough in a day. Since 1877, the following has applied in Switzerland: 1 Juchart = 36 ares = 3,600 m\u00b2. You can still come across it today in old land registry documents.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion on the square metre calculator<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For most areas, multiplying the length by the width is enough to work out the square metres. Break complex shapes down into simple shapes and add them together. You need to be careful with sloping roofs, when using centimetres instead of metres, and when converting to other units. That\u2019s exactly where the calculator saves you time and helps you avoid mistakes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Are you still missing a conversion for areas or prices?
