How to Use Our Bolt Pattern Converter Calculator
Our calculator is simple and precise, designed for ease of use. Here’s how it works:
- Enter Number of Lug Bolts:
- Input the number of bolts, e.g., 5 for a 5-lug pattern, typically 4 to 8.
- Enter Bolt Circle Diameter (mm):
- Add the diameter of the circle formed by the bolts, e.g., 114.3 mm, found in your vehicle’s specs or wheel documentation.
- Select Output Unit:
- Choose millimeters (mm) or inches (in) for the bolt circle diameter.
- Click Calculate:
- The calculator outputs:
- Bolt Pattern: The standard format, e.g., 5×114.3 (mm) or 5×4.5 (in).
- Number of Lug Bolts: Your input for reference.
- Bolt Circle Diameter: The diameter in your chosen unit.
- A bar chart compares bolt circle diameter and number of bolts visually.
- The calculator outputs:
Example: Converting a 5×114.3 Bolt Pattern
Suppose your vehicle has a 5×114.3 bolt pattern, and you want to see it in inches. Using our calculator:
- Inputs:
- Number of Lug Bolts: 5
- Bolt Circle Diameter: 114.3 mm
- Output Unit: Inches
- Outputs:
- Bolt Pattern: 5×4.5
- Number of Lug Bolts: 5
- Bolt Circle Diameter: 4.5 inches
- Chart: Shows bolt circle diameter (4.5 inches, blue) vs. number of bolts (5, pink).
The chart helps you visualize the bolt pattern for better understanding.
Understanding the Inputs and Outputs
Here’s what each input and output means:
- Number of Lug Bolts: The count of bolts securing the wheel, e.g., 4, 5, or 6.
- Bolt Circle Diameter: The diameter of the circle formed by the bolt centers, in mm or inches.
- Output Unit: Converts the bolt circle diameter to your preferred unit (mm for precision, inches for some markets).
- Bolt Pattern: Combines lug count and diameter (e.g., 5×114.3), the standard format for wheel compatibility.

Why Bolt Patterns Matter
A bolt pattern, such as 5×114.3, defines the number of lug bolts and the diameter of the circle they form. Getting it right is essential for:
- Fitment: Ensures wheels mount securely to your vehicle’s hub.
- Safety: Prevents wheel wobble, loose bolts, or uneven stress on components.
- Compatibility: Confirms new wheels match your car’s specifications.
- Aesthetics: Allows you to upgrade to custom wheels with confidence.
Our Bolt Pattern Converter Calculator helps you verify or convert your bolt pattern, making wheel shopping hassle-free.
Tips for Choosing the Right Bolt Pattern
- Check Vehicle Specs: Find your bolt pattern in your car’s manual or on the hub.
- Verify with Wheels: Confirm new wheels match your vehicle’s bolt pattern.
- Consider Adapters: Wheel adapters can adjust bolt patterns but require professional installation.
- Pair with Other Tools: Use our Wheel Offset Calculator for complete fitment.
- Consult a Pro: For complex upgrades, get a mechanic’s advice.
