What is lot size

Lot size, as the name suggests, refers to the size of the land that your property is on. Typically, it is expressed in square feet or in acres. Of course, it is a metric for understanding how large the property actually is.

Sometimes you might purchase the lot and receive all of the essential information regarding how big it is, or sometimes you might inherit land and may not be able to find this information immediately. In situations where you do not have access to the size of your lot, you might be wondering how you can find this information.

Luckily, there is still a solution.

Using specific technology available today, you can either ascertain the dimensions based on satellite images, or use a calculator to work out things like surface area.

Why is lot size important?

Knowing your lot size can save you a lot of time and money, as it can be an expensive mistake to purchase a metal building which is too big for your property.


Similarly, getting a metal building which is too small means that you can’t utilize it entirely for your needs, which can also end in frustration.

Knowing the size of your lot helps you understand which building projects are realistic to pursue on your property. Not only will you understand how much space you have for these projects, but you will know how much space will be left over. After all, you probably don’t want a project that is going to fill the majority of your available space, leaving you with no open landscape.

Lot size is also important for determining the value of your land. This is important if you are looking to sell, or even looking to purchase a lot. Lot size is a key metric in determining value. Of course, the bigger the lot, the more valuable the land, but it also depends where this land is located.

Size vs. Shape

Another aspect that is very important to understand is lot size vs. lot shape. While it is important to understand the overall size of your land, it is also quite valuable have an outline of the shape. While most lots tend to be rectangular, there are exceptions where land is in irregular shapes.

Any building project should consider size, shape, and any other relevant considerations such as terrain or elevation. Basically, you want a full picture of your property before undertaking any building projects.

How can I benefit from having accurate dimensions?

Having accurate dimensions can help your metal building supplier to both confirm that your building is suitable for space, but also create 3D CAD drawings to show you what your property will look like.

This can be very helpful when you are going through the approval phase of your purchase, so you can confirm that you are happy with the plans.

Plus, having this information means that when you are purchasing land, you can make sure it is the right size.

How can I measure my lot size?

There are several ways that you can effectively measure, or calculate, the area of your lot.

First option

Firstly, potentially the most time-consuming method is to manually measure your lot size by walking the perimeter of your lot.

Of course, you could do it the old fashioned way and walk around the property line with a measuring tape or measuring wheel. However, this method of measurement is very time consuming, and it is easy to make small errors which may throw off the math overall, leading you to incorrectly calculate the total square footage. If you’re intent on this method, be sure to do so very carefully and accurately.

Luckily, you can also do this using your smartphone.

Firstly, by using Google maps, you can utilize GPS, so while you walk the perimeter of your lot, your movements will be tracked and leave you with accurate dimensions. This is quite a bit easier than using a measuring tape, as the phone does the measurements for you as you walk.

Another option is to drop markers on your phone. However, it is unlikely that you will be accurate by using your finger to select these points, rather than using GPS.

Second option

The second option requires documentation or a deed which will traditionally include information regarding the size of your lot. Either with detail or with figures you can use.

Using some online calculators, sometimes you can input the dimension information including width and length, and calculate the total surface area of your lot.

This can help you come up with a single number which can help your metal building company find the best fit for you.

Of course, this is the preferable option if you have access to the information. Just be sure that the information is up to date, and there haven’t been changes or additions to the size of the lot since then. However, it is the case that sometimes this information is simply not available.

Third option

The third option is to utilize an online service such as ‘FindLotSize’ or ‘DaftLogic’, which use Google Maps to find the location of your lot.

Then, you can use this same imagery to work out how big your lot is.

They can do this using the same functionality as Google Maps uses to measure the distance between your location and your destination.

All you have to do is find your lot using the address, and then you will be able to find out the measurements using the pictures.

The Right Option For You?

So out of the above three options, which is the right method? As with any choice, it really depends on your own preferences. You might simply be more comfortable with tools such as a measuring wheel than with a smart phone.

At the end of the day, the right option is simply the one that you prefer. However, be sure not to sacrifice accuracy in making this decision. Measuring the lot precisely should remain your top priority.

What is the average lot size?

In cities, the average lot size has dropped below one-fifth of an acre, when only a few years ago the average was higher.

So, this means less space for each home or establishment in cities in America.

The average lot size is around 8,600 square feet.

Can I build multiple homes on one lot?

This depends entirely on your geographic location, as it hinges either on the size of your plot, or the rules and regulations of the area.

Sometimes, you might have a single 10-acre lot for example, but building multiple homes requires you to split your land into a couple of lots or more, depending on the building size.

It also depends how many separate buildings you want.

So, as with any building project, you need to fully examine your local rules and guidelines before you begin. Your municipality likely has a help-line or service centre to help with these types of inquiries.

How many buildings can I construct per acre?

Taking an acre of land, for instance, traditionally you can build around five homes on your this acre.

This gives you approximately 8,600 square feet per home.

How do I work out how many acres I have?

You can work out your lot size regarding acres by merely multiplying the length of your lot by the width.

This will give you the square ft of your lot.

Then, you divide this number by 43,560 to work out the full acreage of your property.

For instance, if your lot were 130,680 sqft, you would divide it by 43,560, and in the result, you would be left with a lot dimension of three acres.
