How Many 50x100 Plots Are in an Acre? Plot Sizes in Kenya Explained
Eddy NdumiaHead of Technology & Digital Products, Famyard Enterprises7 min read
"How many plots are in an acre?" is one of the first questions every land buyer in Kenya asks, usually followed by "is a 50 by 100 an eighth of an acre?" The answers are simple once you see the numbers, and knowing them helps you compare prices and spot listings that are smaller than they sound.
The short answer
- An acre holds about 8 plots of 50x100 ft in practice. On paper it is 8.7, but roads and boundaries take up some land, so most acres subdivided into 50x100 plots give 7 to 8 plots.
- A 50x100 ft plot is 5,000 square feet, which is about 464.5 square metres, 0.115 acres or 0.046 hectares.
- An exact eighth of an acre is 5,445 square feet (about 505.9 square metres). So a 50x100 plot is about 8% smaller than a true eighth of an acre, even though people in Kenya often call it "an eighth".
The numbers
| Measure | Square feet | Square metres | Acres | Hectares |
|---|---|---|---|---|
| 50x100 ft plot | 5,000 | 464.5 | 0.115 | 0.046 |
| 1/8 acre | 5,445 | 505.9 | 0.125 | 0.051 |
| 100x100 ft plot | 10,000 | 929.0 | 0.230 | 0.093 |
| 1/4 acre | 10,890 | 1,011.7 | 0.250 | 0.101 |
| 1/2 acre | 21,780 | 2,023.4 | 0.500 | 0.202 |
| 1 acre | 43,560 | 4,046.9 | 1.000 | 0.405 |
| 1 hectare | 107,639 | 10,000 | 2.471 | 1.000 |
Useful conversions:
- 1 foot = 0.3048 metres
- 1 square metre = 10.764 square feet
- 1 acre = 43,560 square feet = 4,046.86 square metres
- 1 hectare = 10,000 square metres = 2.471 acres
How many 50x100 plots in...
| Area | Plots on paper | Plots in practice (after roads) |
|---|---|---|
| 1/4 acre | 2.2 | 2 |
| 1/2 acre | 4.4 | 4 |
| 1 acre | 8.7 | 7 to 8 |
| 1 hectare | 21.5 | 18 to 20 |
| 5 acres | 43.6 | 36 to 40 |
The "in practice" column assumes some land goes to access roads and the shape of the land is not a perfect rectangle. A long, narrow parcel or one with a road along two sides can lose more. A well-shaped parcel next to an existing road can lose less.
50x100 in metres
A 50x100 ft plot measures 15.24 m by 30.48 m. That is the size in a perfect rectangle. On real survey plans, plots are rarely exact rectangles, because they follow the shape of the land and the roads. A plot sold as 50x100 may be 15 m by 31 m, or have slightly angled sides, and still have an area close to 465 m².
For example, the plots on Famyard's Chaka Lane 15 survey plan are each about 450 m², which you can check on the estate's interactive 3D plan, where tapping a plot shows its area and the length of each side.
Why "an eighth of an acre" is not quite right
In Kenya, a 50x100 plot is commonly called an eighth of an acre. It is close, but not the same:
- 1/8 acre = 5,445 sq ft
- 50x100 = 5,000 sq ft
The difference is 445 sq ft, or about 41 m². That is roughly the size of a small bedroom and a bathroom. It does not matter much for a single plot, but if you are comparing a "per acre" price with a "per plot" price, it does.
Example: If an acre is priced at KSh 2,000,000, an exact eighth of it is worth KSh 250,000. A 50x100 plot is about 0.115 acres, so the same rate gives about KSh 229,600. (These are round example figures, not Famyard prices.)
Why 8.7 becomes about 8
The raw maths is simple. An acre is 43,560 square feet and a 50x100 plot is 5,000 square feet, so 43,560 divided by 5,000 is 8.712. That is the 8.7 you see in tables.
You cannot sell 0.712 of a plot, so the first step is to round down to 8. The second step is the real reason: land that is divided into plots needs roads.
- Access roads take a strip of the land. A 9 m road through an acre uses a lot more of it than most people expect.
- Road reserves and turning space at the edges and corners are also taken out.
- The shape of the land is rarely a perfect rectangle, so some pieces are left over that are too small or odd to sell as a 50x100.
Put together, it is common to get 7 or 8 full plots from an acre once the roads are cut. A larger parcel loses a smaller share of its area to roads than a single acre does, because the road network is spread over more plots. That is why the hectare row gives 18 to 20 against the 21.5 on paper, a smaller gap in proportion.
If someone tells you that an acre will give you exactly 8.7 plots, they are quoting the arithmetic, not the layout.
How the 3D estate maps show plots on the ground
Numbers on a table are one thing. Seeing the plots laid out on the land is another. Famyard's 3D estate maps are drawn from the survey plans, so each plot is in its real position and shape, with the roads between them.
The maps are live on Mweiga/Kanyagia, Naru Moru, Ruring'u (Kangaita), Wiyumiririe, Tetu (Ihururu) and Chaka Lane 15. You can open any of them from the properties page. More estates are being added.
Here is what the maps help you see:
- How the roads take land. Look at an estate from above and you can see why an acre does not simply divide into 8.7 plots.
- Plot shapes. Not every plot is a perfect 15.24 m by 30.48 m rectangle. Corner and edge plots follow the roads and boundaries.
- Status. Plots are coloured green for available, amber for reserved and grey for sold, following our office records.
- Plot details. Tap a plot to see its number and status. A WhatsApp button then sends us a message about that plot.
If you are comparing a per-acre price with a per-plot price, open the estate map first. It shows how much of the land is plots and how much is roads.
Buyers abroad can use the same maps to choose a plot, and Famyard accepts Bitcoin and USDT as well as bank transfer. The price is agreed in shillings. See our diaspora page for how buying from abroad works.

| 40x60 ft | 2,400 sq ft (223 m²) | Common in dense estates near Nairobi |
| 40x80 ft | 3,200 sq ft (297 m²) | Common in Kiambu, Machakos and Kajiado estates |
| 50x100 ft | 5,000 sq ft (464.5 m²) | The standard in Nyeri, Laikipia and most of Kenya |
| 100x100 ft | 10,000 sq ft (929 m²) | Sometimes called a quarter acre (a true quarter is 10,890 sq ft) |
If a listing just says "a plot", ask the exact size. Our guide comparing Nyeri and Kiambu explains why plots are getting smaller near Nairobi.
What fits on a 50x100 plot
A 50x100 plot is enough for:
- a 3 or 4 bedroom bungalow with a garden and parking;
- a maisonette with a small yard;
- a small block of rental units, if county zoning allows;
- a kitchen garden, fruit trees and a few chickens alongside a house.
You will need to leave space for building lines and setbacks set by the county, and for a septic tank or soak pit if there is no sewer. Our building permits guide explains the approvals, and our guide to choosing a house design for your plot covers layout.
How to check the real size of a plot
- Read the title. It shows the registered area, usually in hectares.
- Run an official search. It confirms the area on the register. See our title deed verification guide.
- Look at the survey (mutation) map. It shows the plot's shape and side lengths.
- Check the beacons on the ground. Measure between them if you can. Our guide to land surveying and beaconing explains what to look for.
Titles in Kenya usually give the area in hectares. A 50x100 plot shows as about 0.0465 ha. If you see 0.045 or 0.046, that is a normal 50x100 plot. If you see 0.04 or less, the plot is smaller than 50x100.
