Enter the initial dimension and the reference dimension into the Dimension Ratio Calculator. The calculator will evaluate and display the Dimension Ratio.

## Dimension Ratio Formula

The following formula is used to calculate the Dimension Ratio.

**DIMR = ID / RD**

- Where DIMR is the Dimension Ratio
- ID is the initial dimension
- RD is the reference dimension

## How to Calculate Dimension Ratio?

The following example problems outline how to calculate Dimension Ratio.

Example Problem #1:

- First, determine the initial dimension.
- The initial dimension is given as: 789.

- Next, determine the reference dimension.
- The reference dimension is provided as: 1000.

- Finally, calculate the Dimension Ratio using the equation above:

DIMR = ID / RD

The values given above are inserted into the equation below and the solution is calculated:

DIMR = 789 / 100 = .789

Example Problem #2:** **

For this problem, the variables required are provided below:

initial dimension = 800

reference dimension = 1600

Test your knowledge using the equation and check your answer with the calculator above.

DIMR = ID / RD** = ?**
