There are various sizes in which garage doors are available. These standard sizes are usually available in the market but can be problematic when you own a garage that does not have a standard size. In that case, you can look at various companies to see which one suits your needs. However, most companies now produce many garaged door sizes to fit a variety of car sizes.
One standard size of doors is golf cart doors. These doors usually have measurements of 5 by 7 feet, 5 by 8 feet, 6 by 7 feet and 6 by 8 feet. If you have a garage door opening that is slightly smaller than these measurements, then you should purchase a garage door that is three inches to a foot shorter. Such garage door sizes are also available in the market.
Single car doors are bigger in size. They are available in sizes of 8 by 7 feet, 8 by 8 feet, 9 by 7 feet, 9 by 8 feet, 10 by 7 feet and 10 by 8 feet. The width for these garage doors is the same but if you require a shorter door in height, then such a door is likely to be available in single car doors as well.
Double car doors are the largest since they come in sizes ranging between 12 by 7 feet, 12 by 8 feet, 14 by 7 feet, 14 by 8 feet, 16 by 7 feet, 16 by 8 feet, 18 by 7 feet and 18 by 8 feet. Again, standard width garages are available but shorter heights can also be met by those sizes being available.
Some manufacturers do not offer all these sizes because of the manner in which certain doors are built. Also, extremely windy zones do not manufacture doors that are 18 feet wide. In such a case, insulation would be the best alternative.
To make sure you get the correct measurement, measure the width and then the height since all measurements are stated in the width-height format. If you cannot measure your own garage door, a professional can determine the size for you for free.
