What Is a Cubit?
Before modern measuring tools existed, people often used parts of the human body as measuring standards.
The cubit was one of the oldest units of length ever used.
Origin of the Cubit
The word “cubit” comes from the Latin word cubitum, meaning elbow.
Traditionally, a cubit represented the distance from:
- The elbow
- To the tip of the middle finger
Because arm lengths differ from person to person, cubits were not perfectly standardized.
Over time, civilizations established official cubit measurements for construction and trade.
Why Ancient Civilizations Used Cubits
Cubits were practical because everyone carried the measuring tool with them—their own arm.
Ancient cultures using cubits included:
- Egyptians
- Hebrews
- Babylonians
- Assyrians
- Greeks
Many famous ancient structures were designed using cubit measurements.
How Many Feet Is 5 Cubits Based on Different Standards?
One reason people get different answers is that several types of cubits existed.
Standard Hebrew Cubit
Most biblical scholars use:
- 18 inches
- 1.5 feet
Calculation:
5 × 1.5 = 7.5 feet
Egyptian Royal Cubit
The Egyptian royal cubit measured approximately:
- 20.6 inches
- 1.72 feet
Calculation:
5 × 1.72 = 8.6 feet
Longer Biblical Cubit
Some researchers believe certain biblical passages used a longer cubit of roughly:
- 20.4 inches
- 1.7 feet
Calculation:
5 × 1.7 = 8.5 feet
Comparison Table
| Cubit Type | Length of 1 Cubit | 5 Cubits |
| Common Cubit | 18 inches | 7.5 feet |
| Hebrew Cubit | 18 inches | 7.5 feet |
| Royal Cubit | 20.6 inches | 8.6 feet |
| Long Cubit | 20.4 inches | 8.5 feet |
For most purposes, especially biblical interpretation, 5 cubits equals approximately 7.5 feet.

Why Cubit Measurements Can Vary
Many people assume there was only one cubit. In reality, several standards existed.
Common Cubit
The common cubit measured:
- Approximately 18 inches
- Based on the average forearm
This is the measurement most often used in biblical studies.
Royal Cubit
Kings and builders needed more consistent measurements.
As a result, some cultures created official cubits.
The Egyptian royal cubit was:
- About 20.6 inches long
Builders used rods marked with precise units.
Biblical Cubit
The Bible occasionally refers to measurements that may have used either:
- The common cubit
- A longer sacred or royal cubit
This explains why scholars sometimes disagree about exact dimensions.
Biblical Examples of Cubit Measurements
Understanding cubits becomes much easier when examining famous biblical structures.
Noah’s Ark
According to Genesis, Noah’s Ark measured:
- 300 cubits long
- 50 cubits wide
- 30 cubits high
Using the common cubit:
| Measurement | Feet |
| Length | 450 ft |
| Width | 75 ft |
| Height | 45 ft |
This reveals how enormous the Ark would have been.
The Ark of the Covenant
The Ark of the Covenant measured:
- 2.5 cubits long
- 1.5 cubits wide
- 1.5 cubits high
Converted into feet:
- Length: 3.75 feet
- Width: 2.25 feet
- Height: 2.25 feet
Solomon’s Temple
The Bible records numerous temple dimensions using cubits.
Modern conversions help historians estimate:
- Building size
- Room dimensions
- Construction methods
What Does 5 Cubits Look Like in Real Life?
Numbers can be hard to visualize.
Let’s compare 5 cubits, or roughly 7.5 feet, to familiar objects.
Everyday Comparisons
5 cubits is approximately:
- The height of a standard basketball hoop rim (10 feet) minus 2.5 feet
- The height of many interior room ceilings
- The length of a large sofa
- The height of a tall bookshelf
Human Comparison
An average adult stands:
- About 5.5 to 6 feet tall
Therefore, 5 cubits is noticeably taller than most people.
Vehicle Comparison
A midsize SUV is often:
- Around 6 to 7 feet wide
So 5 cubits is close to the width of many vehicles.
How to Convert Cubits to Feet
Converting cubits is simple when using the standard cubit.
Step 1: Determine Cubit Length
Most biblical conversions use:
1 cubit = 1.5 feet
Step 2: Multiply
Formula:
Feet = Cubits × 1.5
Example
5 cubits:
5 × 1.5 = 7.5 feet
Additional Examples
| Cubits | Feet |
| 6 | 9 |
| 8 | 12 |
| 12 | 18 |
| 25 | 37.5 |
Common Mistakes When Converting Cubits
