What does a lot size of 72X70X99X45X26 even mean, and how large is it?

When you search for a home on my website and view the "Detailed Information" link for a home, you will see something like this:Lot size portion of customer display

If you look at the "Lot Size" field, you will see a set of numbers. If the numbers are something like 100×100, it’s easy: a square lot with each side measuring 100ft. But 72x70x99x45x26? Which side is which dimension, and what is the total overall size?

Let’s start with the basics. Standard convention says that the street side is the first dimension listed, and then the other dimensions follow clock-wise. For example, if you have a lot size of 60×130, the street side measures 60ft and the lot goes back 130ft.

If there are only 2 dimensions listed (60×60 or 60×130, for example), it implies that the lot is either square- or rectangular- shaped.

If there are 3 dimensions listed (60x80x100, for example), the lot is a triangle, with the street side measuring 60ft. Triangular-shaped lots are not very common.

As soon as you have more than 3 dimensions, it becomes increasingly difficult to determine the shape of a lot. You may see 60x130x60x130. Although the opposite sides measure the same length, the lot is not necessarily rectangular; it could be rhombus-shaped. With 4 completely different dimensions, it helps to draw it out on paper to get a better approximation of the lot size. When you go look at a house, you can usually get visual clues to determine where the property line ends (fence, tree lines, etc.), which helps to simplify visualizing the size.

Going back to our earlier example of 72x70x99x45x26, we have 5 dimensions, or 5 sides. At this point, it’s practically impossible to determine the shape of a lot without actually seeing it. Fortunately, I have plat maps which depict what the lot size and layout are for any piece of land in Champaign County. In our example, the dimensions represent a corner lot (392-003 in picture): Plat map of sample lot

Plat maps are a great resource. I use them often to verify lot sizes for clients and to understand the all-so-common term that some lazy agents use which you can see in this customer display:
Lot size: Irregular

Whether you’re looking for a home with a small lot, a large lot, or an "irregular" lot, I can help you find it. No detail is too small to double-check. I can show you the plat maps, and we can verify that you are getting all of the land that the seller is claiming to be selling (believe it or not, some agents have been known to write down the wrong lot size).

  1. Hi,

    What does it mean in terms of lot size when it says
    .17 square feet? does that mean .17 of an acre?
    If so, what is the measurement in length x width dimensions? Thanks for you help.

  2. Hi Judi,

    Thank you for your question. I am making the assumption that you saw an ad for a home where the lot size was listed as “.17 square feet”. My guess is that the seller’s agent didn’t bother calculating the actual square footage, and just put in the acreage. Otherwise, it is one tiny lot! There are 43,560 square feet in 1 acre. A lot size of .17 acres would then be 43,560 X .17 = 7,405.2 square feet, a much more common size (similar to a 62 X 120 lot).

    As far as the dimensions, Area = Length X Width. In this case, we do not know either of the 2 dimensions, assuming that it is even a rectangular lot. There is really an infinite number of possibilities. The only way to tell is to know what the lot looks like. What is the address of the property? I can tell you the exact shape of the lot, and confirm the size.

  3. Hi There,

    I am currently trying to buy a house and i have looked at about 27 different ones over the internet each one has a LOT SIZE but it show the size like this (ie: Lot Size: 831) i think that’s the total but whats the measurements. Please Help. THANK YOU


  4. Hi George,

    Do you know which unit of measurement the 831 refers to (square meters, acres, etc.)? Like I told Judi, it’s practically impossible to determine the lot dimensions using the total lot size figure. Do you have a link to one of the houses that you’ve seen that has a lot size like that? I’d love to take a look and see how I can help.

    Happy New Year,

  5. Hello,

    I am looking for some houses and would like to get an advise. For a house of 2000 sq ft what would be an average lot size? One of them I have seen is 87*179 lot size for a 2050 sqft home, is that real good?


  6. Dear VB,

    For the Champaign/Urbana area, a lot size of 87 x 179 is of above average size. Here, a lot size for the size home that you specified would probably be closer to 80 x 120. Of course, this also depends on whether the home is a single-story or a two-story. Single-story homes tend to be on slightly larger lots, since the footprint of the home is larger due to the living space being all on one level. If you are curious about some specific homes, email me and we can discuss it.

  7. How do I confirm, wht is total sft of the lot..when they specified lot size:82*111*109*161*69.

    Is its gud size of lot in Plymouth,mn..for single family home?

    Thank You

  8. Hi venkat,

    Thank you for your questions. I did some research into Plymouth, MN (I’m in east-central Illinois), and it appears that the average lot size for single family homes in Plymouth is about .47 acres. Assuming a normal rectangular lot, this roughly translates to a lot measuring about 100 feet wide by 205 feet deep. The lot size that you listed has 5 dimensions, so it is very difficult to really assess how large it is without making further assumptions about the general shape of the lot. Just looking at the numbers that you specified makes the lot seem pretty average-sized for the area, but I am assuming that each corner is more than 90 degrees.

    For a better answer, I would highly recommend that you map out the address of the home you’re considering and switch into a terrain- or ‘bird’s eye-‘ view, where you can use visual cues (like tree lines, fences, rivers, lawn color changes, etc.) to get a good impression of the shape of the lot. Or, if you are working with an agent, ask them to show you the plat map for the home. If you need to find an agent in Plymouth, just let me know!

    Have a great day,

  9. Hi Ana,

    “TBV” likely stands for “to be verified”. “TBD” (to be determined) is also another common one that you may see. This can happen due to several reasons, like if the lot is in a new development where the exact property boundaries have not been drawn yet. Also, it could be as simple as an agent not having verified the lot size for a property prior to putting it on the market. Please let me know if you have any other questions, and good luck with your home search!

  10. hi i was wondering if you can show me in a drawing or pic or image,.. sry… how big is a lot 73.8 x 107.6 = 7940.88. i bough this lots in texas and both are the same size.. but i want to see as how big it is, b4 i decide to build on both or just convert them into one…
