However, if the room is irregularly shaped, you may need to divide the space into smaller areas. Here\u2019s how to calculate the square footage of a room:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-measuring-a-square-or-rectangular-room\">Measuring a Square or Rectangular Room<\/h3>\n\n\n\n<p>To calculate the square footage of a square or rectangular area, measure its length and width in feet, and then multiply these two measurements.<br><br>For example, if a room is 11 feet long and 15 feet wide, then the total square footage of that room is 165 square feet (11 \u00d7 15 = 165).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"943\" loading=\"lazy\" src=\"https:\/\/www.zolo.ca\/blog\/wp-content\/uploads\/2024\/08\/155481-How-to-Calculate-Square-Footage_InLine-image-1_Superside_D1-1024x943.png\" alt=\"How to calculate square footage of a rectangular or square room\" class=\"wp-image-23998\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Measuring an L-shaped Room<\/h3>\n\n\n\n<p>If the room is not perfectly square, you will need to split the room into box-shaped sections.<br><br>For instance, if you have an L-shaped kitchen, break the room into two separate boxes.

In that case, you\u2019ll need to repeat the process of splitting the room into box sections, only this time, one of the boxes is a triangle.<br><br>Measure the length and width of each box to calculate each section\u2019s square footage.

To accurately measure the gross living area, measure each room and add the measurements together. In some cases, exterior measurements will be used to calculate the GLA.&nbsp;<\/p>\n\n\n\n<p>On the other hand, total living area (TLA) often includes finished basements and separate, finished buildings, such as guest houses.

However, two different appraisers could come up with slightly different measurements for the same home, but the variance should be minimal. <\/p>\n\n\n\n<p>Virtual tours, 3D floor plans, and laser-guided square footage measurements are now considered industry standards for measuring residential real estate, which can reduce the likelihood of inaccurate measurements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-to-include-in-a-home\u2019s-square-footage?\">What to Include in a Home\u2019s Square Footage?<\/h2>\n\n\n\n<p>Not all space in your home should be included in your home\u2019s gross living area. In general, you can include rooms in your home with the following attributes in the home\u2019s square footage calculations:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A ceiling height of seven feet or higher<\/li><li>Walls with drywall or similar wall covering<\/li><li>Flooring<\/li><li>Heating and cooling<\/li><\/ul>\n\n\n\n<p>The rooms that typically count towards a home\u2019s gross living area, if they are finished, include:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Living room<\/li><li>Family room<\/li><li>Kitchen<\/li><li>Dining room<\/li><li>Bathrooms<\/li><li>Bedrooms<\/li><li>Porch with heating and cooling system (if applicable)&nbsp;<\/li><\/ul>\n\n\n\n<p>Unfinished and below-grade areas in the home that are not included in the home\u2019s gross living area consist of:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Garage<\/li><li>Attic<\/li><li>Rooms with a sloping ceiling&nbsp;<\/li><li>Basement (finished or unfinished)<\/li><li>Separate storage areas, such as sheds<\/li><li>Pool house<\/li><li>Guesthouse<\/li><li>Detached in-law suites, coach houses, or lane houses<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"resale-vs.-new-build-square-footage-measurement-considerations\">Resale vs. New Build Square Footage Measurement Considerations<\/h2>\n\n\n\n<p>In resale homes, square footage calculations should only include indoor living space. Room measurements should be taken from the inner wall to the inner wall, also known as \u201cpaint to paint\u201d measurements.\u200b<\/p>\n\n\n\n<p>In contrast, newly built homes may base their square footage calculations on outer wall-to-outer wall measurements. Depending on the materials used, this can mean a significant difference between the reported calculation and the actual living space.<\/p>\n\n\n\n<section class=\"wp-block-zolo-related flex items-center py-6 leading-tight border-t border-b border-blacklight undefined\"><p class=\"font-serif pr-6 md:pr-12 mr-6 md:flex-shrink-0 border-r border-blacklight\">Related content<\/p><p class=\"related-link w-full my-0\"><a href=\"https:\/\/www.zolo.ca\/blog\/canada-first-time-home-buyer\">Canada First-Time Homebuyer Guide<\/a><\/p><\/section>\n\n\n\n<p>Even trickier are the square footage measurements developers provide for buildings and homes that are not yet built. These pre-construction measurements are tricky because there is no physical structure to measure. While floor plans state square footage, you shouldn\u2019t rely on sales brochures or other materials, including builder floor plans, for accurate measurements.<\/p>\n\n\n\n<p>Instead, pre-construction home and condo buyers should hire a <a href=\"https:\/\/www.zolo.ca\/blog\/real-estate-lawyer-guide\">real estate lawyer<\/a>. These knowledgeable professionals can confirm if the sales contract contains all the necessary details for a new build purchase. Regardless of your decision, the key is to document all measurements, agreements, and promises in writing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Be Cautious of Price Adjustment Clauses for New Builds<\/h3>\n\n\n\n<p>Another legal dilemma is including a price adjustment clause in a sales contract. This clause allows developers to finalize the sale of a new build even if the final square footage of the sale unit is 15% less (or more) than the square footage calculated in the sales contract.&nbsp;<\/p>\n\n\n\n<p>The dilemma is that the price adjustment clause legally requires the buyer to adjust their final purchase price to match the final square footage sold.<\/p>\n\n\n\n<p>For example, you are purchasing a 1,000-square-foot condo for $250 per square foot. When the unit is complete, the living space is 1,150 square feet\u201415% larger than the unit size in the sale contract. Based on the price adjustment clause, you must pay for the additional cost of the extra space.<\/p>\n\n\n\n<p>To avoid any price shocks, seek the help of legal professionals who understand your new build sales contract.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-to-do-if-you-bought-a-house-with-inaccurate-square-foot-measurements\">What to Do if You Bought a House With Inaccurate Square Foot Measurements<\/h2>\n\n\n\n<p>If you find out a house you bought is priced based on inaccurate square foot measurements, you have several options. The right solution will depend on where you are in the <a href=\"https:\/\/www.zolo.ca\/blog\/glossary\/agreement-purchase-sale\">purchase and sale agreement<\/a>.&nbsp;<\/p>\n\n\n\n<p>If you are still negotiating, one option is to ask for a price reduction based on the prices of comparable homes. If the seller refuses to adjust the price, you may have legal grounds to withdraw from the purchase contract without incurring any penalties. Some sale agreements may include a disclaimer stating that the buyer should verify all measurements. In such cases, you may consider hiring a professional for accurate measurements before proceeding with the purchase.<\/p>\n\n\n\n<section class=\"wp-block-zolo-related flex items-center py-6 leading-tight border-t border-b border-blacklight undefined\"><p class=\"font-serif pr-6 md:pr-12 mr-6 md:flex-shrink-0 border-r border-blacklight\">Related content<\/p><p class=\"related-link w-full my-0\"><a href=\"https:\/\/www.zolo.ca\/blog\/how-to-find-a-real-estate-agent\">How to Find a Real Estate Agent<\/a><\/p><\/section>\n\n\n\n<p>After closing the sale, you may need to consider hiring legal counsel and either sue your agent, the seller&#8217;s agent, or the seller.

Next, multiply the length and width measurements to determine the total square footage. The simple formula is length (in feet) x width (in feet) = total sq ft.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How many square feet is a 12&#215;12 room?<\/h3>\n\n\n\n<p>To calculate the square footage area of a 12\u2019 by 12\u2019 room, multiply 12 x 12. For example:<\/p>\n\n\n\n<p><strong>12\u2019 x 12\u2019 = 144 sq ft.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you calculate floor area in m2?<\/h3>\n\n\n\n<p>Metres squared, or m2, is calculated by measuring the room&#8217;s length and width in metres and multiplying the length and width measurements together. The simple formula is length (in metres) x width (in metres) = total m2. For example:<\/p>\n\n\n\n<p><strong>5m x 4.5m = 22.5m2<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to calculate square footage for flooring?<\/h3>\n\n\n\n<p>When calculating the square footage of a room for flooring, measure the length and width of the floor area in feet and multiply them to determine the square footage. If the flooring will run through multiple rooms, add the square footage measurements together. For rooms that are irregularly shaped, break the room into rectangular sections.<\/p>\n\n\n\n<p>When measuring for flooring, purchasing an extra 10-15% is recommended to account for wasted materials. For example:<\/p>\n\n\n\n<p>Room measurements: 10\u2019W x 12\u2019L = 120 sq ft<\/p>\n\n\n\n<p>Accounting for waste: 120 x 1.15 = 138 square feet of flooring<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What are the standards when it comes to measuring residential housing in Canada?<\/p>\n","protected":false},"author":112,"featured_media":17742,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[47],"tags":[],"guide":[],"class_list":["post-17736","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-buying"],"acf":[],"zolo_excerpt":"","_links":{"self":[{"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/posts\/17736","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/users\/112"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/comments?post=17736"}],"version-history":[{"count":23,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/posts\/17736\/revisions"}],"predecessor-version":[{"id":25216,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/posts\/17736\/revisions\/25216"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/media\/17742"}],"wp:attachment":[{"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/media?parent=17736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/categories?post=17736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/tags?post=17736"},{"taxonomy":"guide","embeddable":true,"href":"https:\/\/www.zolo.ca\/blog\/wp-json\/wp\/v2\/guide?post=17736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
