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 

To calculate the dimension ratio, divide the initial dimension by the reference dimension.

How to Calculate Dimension Ratio?

The following example problems outline how to calculate Dimension Ratio.

Example Problem #1:

1. First, determine the initial dimension.
   • The initial dimension is given as: 789.
2. Next, determine the reference dimension.
   • The reference dimension is provided as: 1000.
3. 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 = ?
