Aspect Ratio Calculator
How to Use the Aspect Ratio Calculator
Step 1: Select What You Want to Calculate
Begin by choosing what you want to calculate from the dropdown menu labeled "Calculate:". You have four options:
 Aspect Ratio: Calculate the aspect ratio based on the provided width and height.
 Width: Calculate the width when you have the aspect ratio and height.
 Height: Calculate the height when you have the aspect ratio and width.
 Resize / Compare: Compare two sets of dimensions to see how they match up in terms of aspect ratio.
Step 2: Enter the Required Values
Based on your selection, you'll need to enter the appropriate values in the input fields that appear:

Aspect Ratio Calculation:
 Enter the Width and Height.
 Example: If you enter a width of
1920
and a height of1080
, the calculator will determine that the aspect ratio is16:9
, which is a common standard for HD videos.

Width Calculation:
 Enter the Aspect Ratio and Height.
 Example: If you know the aspect ratio is
16:9
and the height is720
, the calculator will compute the width as1280
.

Height Calculation:
 Enter the Aspect Ratio and Width.
 Example: If the aspect ratio is
4:3
and the width is800
, the calculator will determine that the height should be600
.

Resize / Compare:
 Enter two sets of Width and Height values to compare them.
 Example: If you have two images, one with dimensions
1920x1080
and another with1280x720
, the calculator will show you that both share the same aspect ratio of16:9
, and provide the diagonals for both dimensions.
Step 3: Choose Units (Optional)
You can choose the unit of measurement (e.g., pixels, inches, centimeters, millimeters) from the "Units:" dropdown menu. This is particularly useful if youâ€™re working with print media or need precise physical dimensions.
Step 4: Click "Calculate"
After entering your values, click the "Calculate" button. The calculator will instantly provide you with:
 The Actual Aspect Ratio based on your input.
 The Nearest Standard Aspect Ratio if applicable.
 The calculated Width, Height, and Diagonal (for "Resize / Compare" mode).
Step 5: Review the Results
The results will appear in the "Answer:" section, neatly displayed in a table format. This will include the calculated values, allowing you to see the exact aspect ratios and dimensions.
Examples

Example 1: Calculating Aspect Ratio
 Scenario: You have a video with dimensions
1280x720
.  Steps:
 Select "Aspect Ratio" from the dropdown.
 Enter
1280
for Width and720
for Height.  Click "Calculate".
 Result: The calculator displays an aspect ratio of
16:9
, a standard format for widescreen videos.
 Scenario: You have a video with dimensions

Example 2: Finding Width from Aspect Ratio and Height
 Scenario: You need to design an image with a
16:9
aspect ratio, but you only know the height is1080
.  Steps:
 Select "Width" from the dropdown.
 Enter
16:9
for Aspect Ratio and1080
for Height.  Click "Calculate".
 Result: The calculator shows the width as
1920
, which is a common resolution for Full HD images.
 Scenario: You need to design an image with a

Example 3: Comparing Two Sets of Dimensions
 Scenario: You want to compare two banners: one is
1200x600
, and the other is1600x800
.  Steps:
 Select "Resize / Compare" from the dropdown.
 Enter
1200
for Width 1,600
for Height 1,1600
for Width 2, and800
for Height 2.  Click "Calculate".
 Result: The calculator reveals that both banners have the same aspect ratio of
2:1
, making them proportional to each other.
 Scenario: You want to compare two banners: one is
Quick Tips
 Standard Aspect Ratios: The calculator will automatically suggest the nearest standard aspect ratio (like
16:9
or4:3
), which is helpful if youâ€™re aiming for industrystandard dimensions.  Clearing Inputs: Use the "Clear" button to reset the calculator quickly, so you can start a new calculation.
 Unit Flexibility: Donâ€™t worry too much about units when calculating aspect ratiosâ€”theyâ€™re independent of units. However, selecting units can help when working with physical dimensions.
