Choose a metre stick or metric tape measure. Select a metre stick rulerGrass Factory & Eco Organics - Calculating an Area in Square Meters or tape measure with metres (m) or centimetres (cm) printed on it. These tools will make it easier to calculate square metres since they were designed in the same system of measurement.

Grass Factory & Eco Organics - Calculating an Area in Square MetersMeasure the length of the area you’re measuring. Square metres are a unit for measuring area or the size of a two-dimensional object such as a floor or a field. Use your measuring tool to measure one side of the object, from one corner to the other. Write down the result.

If the object is longer than 1 metre, remember to include both the metre and centimetre parts of the measurement. For instance, “2 metres 35 centimetres.”

If you can’t measure the entire length at once, do it in stages. Lay out the measuring tool, then put down a rock or other small object precisely at an easy to remember mark (like 1 metre or 25 centimetres). Pick up the tool and lay it down again, starting at the small object. Repeat until the entire length is covered, and add all your measurements together.Grass Factory & Eco Organics - Calculating an Area in Square Meters

Measure the width. Use the same tool to measure the width of the same area or object. The side you measure in this step should be angled close to 90° away from the length of the object you measured earlier, like two sides of a square next to each other. Write this number down as well.

Unless the object you’re measuring is much smaller than 1 metre, you can round to the nearest centimetre when making your measurements. For instance, if the width is slightly past the 1 metre 8-centimetre mark, just use “1m 8cm” as your measurement, without using decimals or millimetre measurements.

Convert from centimetres to metres. Usually, the measurements won’t divide evenly into metres. Instead, you’ll have a measurement in both metres and centimetres, for example, “2 metres 35 centimetres.” Because 1 centimetre = 0.01 metres, you can convert a centimetre measurement into metres by moving the decimal point two digits to the left.

Here are a couple examples:
35cm = 0.35m, so 2m 35cm = 2m + 0.35m = 2.35m
8cm = 0.08m, so 1m 8cm = 1.08m

Grass Factory & Eco Organics - Calculating an Area in Square MetersMultiply the length and width together. Once both measurements are converted into metres, multiply them together to get the measurement of the area in square metres. Use a calculator if necessary. For example:
2.35m x 1.08m = 2.538 square metres (m2).

Round to a more convenient measurement. If you get a long decimal as an answer, for instance, 2.538 square metres, you’ll probably want to round it to a number with fewer digits, for example, 2.54 square metres. In fact, since you possibly didn’t measure correctly down to the tiniest fraction of a metre, the last digits probably aren’t accurate anyway.Grass Factory & Eco Organics - Calculating an Area in Square Meters In most cases, you can round to the nearest centimetre (0.01m).

Whenever you multiply two numbers with the same units (for instance, metres), the answer is always in the form of that unit squared (m2, or square metres).

You can take the square metre figure and multiply it by three to determine how many rolls of grass you’ll need. Please ensure when you order grass from Grass Factory & Eco Organics that you communicate the square metres or the number of rolls you require.

IMPORTANT: Remember that grass/instant lawn is a natural product supplied in rolls. The grass rolls are not rigid or solid, and is subject to break and have slight deviation in size due to its nature. It is very important to add 10% over and above the actual area size, to have adequate material for coverage.
