What is the diameter of my steering wheel?

In most passenger cars, steering wheels are typically 14 to 16 inches across (about 35 to 40 cm). To know your exact size, you’ll need to measure directly or check your vehicle’s specifications. This article helps you understand typical sizes, how to measure accurately, and what the size means for driving comfort and safety.

Common sizes you’ll encounter

These ranges reflect typical steering wheel diameters across common vehicle classes. Actual size can vary by model and trim.

• Passenger cars: 14.0–15.5 inches (35.5–39.5 cm)


• SUVs and crossovers: 14.5–15.5 inches (37–39.5 cm)


• Pickup trucks and larger light-duty trucks: 15.0–16.0 inches (38–41 cm)


• Sports cars and performance wheels: 14.0–15.0 inches (35.5–38 cm)


• Compact and subcompact cars: 13.5–14.5 inches (34–37 cm)

Note that there are exceptions, especially with models that feature variable-rim designs or special trims. For precise sizing, consult the owner’s manual or measure the wheel directly.

How to measure your steering wheel

To determine the exact diameter, measure across the wheel from outside edge to outside edge along a straight line that passes through the wheel’s center. If the rim is obstructed by spokes or the airbag cover, you can use a string to wrap from one outer edge to the opposite outer edge and then measure the string.

1. Park the car, turn the wheel to the straight-ahead position, and ensure the vehicle is off.


2. Measure the diameter across the wheel's rim, from outer edge to outer edge, along a line that runs through the center. Use a flexible tape measure for accuracy.


3. If the direct rim-to-rim measurement is obstructed, wrap a string around the wheel from one outer edge to the opposite outer edge, mark the length, and then measure the string.


4. Record the measurement in inches; convert to centimeters (1 inch = 2.54 cm) if needed.


5. For irregular rims, take measurements at slightly different positions around the wheel to confirm the diameter is consistent.

With the measurement in hand, you can compare against manufacturer specifications or use it when selecting accessories such as steering-wheel covers or aftermarket rims.

Where to find the exact size

Look in your owner’s manual, the vehicle’s specifications sheet, or the sticker on the driver’s door jamb. Some manufacturers list wheel diameter in the options or accessories section. If you’re unsure, provide your vehicle’s make, model, year, and trim when asking a dealer or retailer for the correct size.

Summary

Steering wheel diameters in modern vehicles typically fall between about 14 and 16 inches (35–41 cm), with small cars toward the lower end and larger trucks and SUVs toward the upper end. To know your exact size, measure straight across the rim or consult the vehicle’s documentation, and account for any spokes or center hubs that could affect the reading. Accurate sizing matters for driving comfort, control, and compatibility with accessories.

How do I know what my wheel diameter is?

Which if we take a look from the side profile. You're actually going to see it starts right about here. And that's going to give us that 18in number and it's going to be the same thing with the width.

Will a 15 steering wheel cover fit a 14.5 steering wheel?

Standard-size covers typically fit steering wheels between 14.5 and 15 inches (37 to 38 cm) in diameter.

What is the diameter of a steering wheel?

The diameter of a steering wheel typically ranges from 14 to 17 inches, though it varies by vehicle type. Smaller wheels, often around 12.6 to 13.8 inches, are common in performance and racing cars for quicker response, while larger wheels, sometimes over 17 inches, are used in trucks and SUVs for better leverage. 
Standard vehicles

• Most everyday cars, trucks, and SUVs have steering wheels between 14 and 15 inches in diameter. 
• Larger vehicles like some trucks and SUVs can have wheels up to 17 inches or even larger to provide more control. 

Performance and racing vehicles

• Smaller diameter wheels, often around 12.6 to 13.8 inches, are used in sports and racing cars. 
• These smaller wheels provide a quicker steering response but may require more effort to turn. 

Other considerations

• When buying an accessory like a steering wheel cover, it is crucial to measure your current steering wheel's diameter to ensure a proper fit. 
• Different size covers are available, such as standard (14.5–15 inches), large (15.5–16 inches), and universal (14–16 inches).
