How to Measure Your Lot Size?

Measure My Lot Size


If you’re looking to build or expand property, it is essential to keep in mind certain factors such as the size of the lot.

As without these points, you won’t be able to discover which metal building type would be best for you, or how big it can be.

Not getting accurate dimensions can sometimes cost a lot of money and time, as you might need to re-evaluate your plans.

In this guide, you’ll find out everything you need to know about lot sizes, including how you can work everything out.

Are you ready?

Let’s get going!

What’s in this guide?

What is lot size?

Lot size, as the name suggests, refers to the size of the land that your property is on.

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.

Luckily, there is still a solution.

Using specific technology available today, you can either ascertain the dimensions based on satellite images, or 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 one which is too small means that you can’t utilise it entirely for your needs, which can also end in frustration.

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 manually by walking the perimeter of your lot.

Luckily, you can do this using your smartphone.

Firstly, by using Google maps you can utilise GPS, so while you walk the perimeter of your lot, your movements will be tracked and leave you with accurate dimensions.

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.

Third option

The third option is to utilise 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.

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.

And, how many separate buildings you want.

How many buildings can I construct per acre?

Taking an acre of land, for instance, traditionally you can build around five homes on your land per 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 sq ft, you would divide it by 43,560, and in the result, you would be left with a lot dimension of three acres.
