A regular roulette of 5 meters long is suitable for most types of rooms. <\/p>\n<p>For large rooms, you can use a laser range finder. This is a more expensive and accurate tool. But at the same time, he still has a small error: \u00b1 1.5-3 mm. In addition, the farmer has a small drawback: it will not work to measure the distance through transparent objects.<\/p>\n<p>To record sizes, you can use a phone or take a notebook and pen.

Then measure each part and summarize the results. <\/p>\n<p>Imagine a room with a length of 6 m, a width of 4 m and the height of the ceilings 2.5 m. The room has a niche and a ledge that must be taken into account in the calculations.<\/p>\n<p>First, draw a room plan and designate all the protrusions and niches. Divide the room into simple geometric shapes:<\/p>\n<p>The main part of the room is a rectangle, a niche is another small rectangle, a protrusion is the smallest rectangle. <\/p>\n<p>Then measure the length, width and height of the main part of the room. Its length is 6 m, width 4 m and height 2.5 m. We calculate the area of \u200b\u200bthe walls of the main part of the room:<\/p>\n<p style=\"text-align: center;\"><strong>Two long walls: 2 \u00d7 (6 \u00d7 2.5) = 2 \u00d7 15 = 30 m2 <\/strong><\/p>\n<p style=\"text-align: center;\"><strong>Two short walls: 2 \u00d7 (4 \u00d7 2.5) = 2 \u00d7 10 = 20 m2  <\/strong><\/p>\n<p style=\"text-align: center;\"><strong>The total area of \u200b\u200bthe walls of the main part of the room: 30 + 20 = 50 m2 <\/strong><\/p>\n<p>Then measure the size of the niche. Its width: 1 m, depth: 0.5 m, height: 2.5 m. We calculate the area of \u200b\u200bthe walls of the niche:<\/p>\n<p style=\"text-align: center;\"><strong>Two side walls: 2 \u00d7 (0.5 \u00d7 2.5) = 2 \u00d7 1.25 = 2.5 m2  <\/strong><\/p>\n<p style=\"text-align: center;\"><strong>Rear wall: 1 \u00d7 2.5 = 2.5 m2 <\/strong><\/p>\n<p style=\"text-align: center;\"><strong>The total area of \u200b\u200bthe walls of the niche: 2.5 + 2.5 = 5 m2 <\/strong><\/p>\n<p>Now we measure the protrusion: its width: 0.7 m, depth: 0.3 m, height: 2.5 m. Now you can calculate the area of \u200b\u200bthe walls of the protrusion: <\/p>\n<p style=\"text-align: center;\"><strong>Two side walls: 2 \u00d7 (0.3 \u00d7 2.5) = 2 \u00d7 0.75 = 1.5 m2 <\/strong><\/p>\n<p style=\"text-align: center;\"><strong>Front wall: 0.7 \u00d7 2.5 = 1.75 m2  <\/strong><\/p>\n<p style=\"text-align: center;\"><strong>The total area of \u200b\u200bthe walls of the ledge: 1.5 + 1.75 = 3.25 m2 <\/strong><\/p>\n<p>Now let's add the walls of the main part of the room, niches and ledges:<\/p>\n<p style=\"text-align: center;\"><strong>50 + 5 + 3.25 = 58 m2 <\/strong><\/p>\n<p>Thus, the total area of \u200b\u200bthe walls of the room room is 58.25 square meters.<\/p>\n<p>For oval or round walls, measure their length (perimeter) with a roulette, pressing it to the surface. Then multiply the resulting figure by the height of the wall. For example, if the perimeter of the walls in the room is 12 m, and the height is 2.5 m, then the area of \u200b\u200bthe walls we count: <\/p>\n<p style=\"text-align: center;\"><strong>Wall area = 12 \u00d7 2.5 = 30 m2 <\/strong><\/p>\n<p>If there are protrusions or niches in the room, add their area.

Take measurements several times and use the average value.<\/p>\n<p>Another mistake is not to take into account windows, doors and other openings in the walls. Carefully measure all the openings and subtract their area from the total area of \u200b\u200bthe wall. If the openings of a complex shape, break them into simple geometric shapes for a more accurate calculation.<\/p>\n<p>Ignoring protrusions, niches, columns and other architectural elements also leads to incorrect calculation. Divide the room into simple geometric shapes and calculate the area of \u200b\u200beach of them separately. Do not forget to add the area of \u200b\u200bprotrusions and niches to the total area of \u200b\u200bthe walls.<\/p>\n<p>The use of various units of measurement (meters, centimeters) in one calculation complicates the process. Always use the same units for all data. <\/p>\n<p>If you do not take into account the different height of the ceilings in different parts of the room, the calculations will be incorrect. Measure the height of the ceilings in several places and use the average value. Consider all changes in height when calculating the area of \u200b\u200bthe walls.<\/p>\n<p>Measurement of inclined surfaces, as direct, also leads to errors in the calculations. To avoid this, use the building level and other tools for accurate measurement of tilts. <\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/aqremont.ru\/view\/images\/blogs_images\/pexels-shkrabaanthony-4981801.jpg\"><br \/>\n<span style=\"color:#7f8c8d;\"><em>Photo: Pay attention, measurements in old houses can be more difficult due to uneven walls and ceilings.
