What are the dimensions of the Bike Handlebar that need to be measured?
What you need to know is which Bike Handlebar Sizes should be measured and understood, and what are their approximate values. Here are the definitions of these in detail.
1. Bike Handlebar Diameter
Bike Handlebar Diameter refers to the diameter of the circular part of the bicycle handlebar. it is measured from the outer edge of one side to the outer edge of the other, generally in millimeters. Generally, the smaller handlebar diameter is 25.4mm. The wider one is about 31.8mm. It is one of the most important parameters when choosing handlebars and handlebars.
Different diameter handlebars directly affect the control of the ride, if you need strong control of the ride, you need to choose a thicker handlebar. if you are a leisurely flexible lightweight rider, then a thinner handlebar may be more suitable. The larger the diameter of the handle, the stronger the structure is usually, able to withstand greater impact and pressure. Suitable for mountain and off-road riding. Increased safety in harsh environments.
2. Handlebar Width
Handlebar Width is the lateral distance of a bicycle handlebar from one end to the other. usually measured in centimeters or millimeters. The width has a great impact on the riding experience especially on the posture and handling of the ride.
Handles of 740mm and above can be used for mountain biking or off-road riding. It can lean forward and extend the rider’s arms outward to enhance handling, which can lead to back pain for long periods of riding. 380mm to 420mm is often used for road riding, this position is more compact and can reduce wind resistance. suitable for fast riding and competition. Narrow handlebars are more responsive when facing strong winds or swerving suddenly.
3. Handlebar Rise
The Handlebar Rise is the vertical distance, usually measured in millimeters. between the grip grip (or clip ring mounted on a bicycle) and the highest point of the handlebar. It determines the height position of the rider’s hands, which affects the riding posture and comfort.
The high-rise handlebars allow riders to stay upright while reducing pressure on their arms, shoulders, and back. Suitable for long-distance and leisure riding. Low Rise makes the body lean forward and can improve speed and wind resistance control, suitable for road riders.
How to Measure Bike Handlebar Sizes?
There are several important dimensions of bicycle Handlebar Sizes that we need to understand and learn to Measure. Below I will show you the detailed steps of how to Measure Bike Handlebar Sizes, as well as the required tools and some standard specifications.
1. Measure Bike Handlebar Diameter
Measure Bike Handlebar Sizes Prepare tools
- Calipers: Vernier calipers or digital calipers are the most accurate tools for measuring diameters.
- Ruler or tape measure: If you don’t have a caliper, you can also use a ruler or tape measure, but with less accuracy.
Measure Bike Handlebar Diameter Sizes
- Method 1: Digital calipers.
- Using a digital caliper is the easiest way to measure, place the caliper in the center of the handlebars and clamp it. As shown in the picture below:

- Method 2: Use a soft tape measure.
- Use a soft tape measure to wrap it around both sides of the handlebars, this is the circumference of the measurement. you need to wrap the tape measure around where you want to attach the Oi to get the circumference measurement. And then divide by Pi… mmm) to get the diameter, for example, 99.9mm / 𝜋 = 31.8mm. This is a standard mountain bike handlebar diameter measured with a tape measure. For example, if the circumference is 99.96 mm, the diameter is about 31.8 mm (99.96 ÷ 3.14). As shown in the picture below:

2. Measure Handlebar Width
1. Measure Handlebar Width Size preparation tool
Measure bike handlebar width Before you need to prepare some tools such as tape measure, caliper, and marker pen.
2. Measure Handlebar Width Sizes
First, locate the curve on the side of the handlebar and use the center of the bend as your starting point. Mark the center of the bend with a marker to ensure accuracy. Next, use a tape measure or caliper, aligning one end with the marked center of the bend. and stretch the tape horizontally across to the center of the bend on the opposite side, ensuring the measurement stays level. Record the width in millimeters. When choosing the right handlebar width, consider your shoulder width. as it’s generally recommended that the handlebar width should closely match your shoulders for optimal comfort while riding.
3. Measure Handlebar Width Standard
The following table is about the Handlebar Width standard, riding style, recommended width, and reasons for selection.
Handlebar Type | Common Width Range | Ideal For | Reason |
---|---|---|---|

Another measurement you need to keep in mind when you Measure Handlebar Rise is its height. The rise of the handlebars determines the distance between the center of the clamping area and the “cover” inside the mountain bike. For detailed steps, please see the following:
- Position the Handlebar Place the handlebar flat on an A4 sheet of paper. Ensure that it is evenly supported and does not move during the process. The paper should be placed on a stable surface to avoid any shifting.
- Mark the Clamp Area Using a pencil, make precise marks on both sides of the clamp area where the handlebar attaches to the stem. Keep the pencil perpendicular to the paper to ensure that your marks are accurate and aligned (refer to Figure 1).
- Draw Lines Along the “Engine Cover” On either side of the handlebar. draw lines along the area where the handlebar begins to transition from a steep incline to a more gradual rise. This transition area is referred to as the “engine cover” (see Figure 2). Make sure your lines are straight and parallel to each other.
- Identify and Mark Midpoints Remove the handlebar from the paper and draw lines connecting the two marks you made on either side of the clamp area. Locate and mark the midpoint of these lines. This midpoint is crucial for the accuracy of your measurement.
- Draw a Vertical Line Place a ruler vertically aligned with the midpoint line you drew. Draw a straight line through the center of the clamp area, extending this line beyond the handlebar’s edges onto the paper (see Figure 3). This vertical line will serve as a reference for measuring the rise.
- Draw a Horizontal Line Place the ruler horizontally at the midpoint of the “engine cover” area. and draw a line that intersects the vertical line you before drew (see Figure 4). Ensure that this horizontal line is level and accurately intersects the vertical line.
- Measure the Handlebar Rise Finally, measure the vertical distance from the intersection point of the horizontal and vertical lines to the midpoint of the clamp area. This distance is your handlebar rise measurement. Use a precise measuring tool to ensure accuracy.
Measure Handlebar Rise Standard
Here’s a table describing handlebar rise standards and their impact on different riding styles:
Handlebar Rise | Common Range | Description | Typical Use | Impact on Riding Style |
---|---|---|---|---|
Low Rise | 0-20mm | Minimal vertical elevation is common in performance bikes. | Road cycling, competitive cycling | Provides a low, aerodynamic position for speed but may reduce comfort over long rides. |
Medium Rise | 20-40mm | Moderate elevation, balancing comfort and performance. | Recreational riding, trail biking | Offers a more upright position, improving comfort and control while maintaining some aerodynamic advantage. |
High Rise | 40-60mm and above | Significant elevation, often found on comfort-oriented bikes. | Casual riding, commuting, cruiser bikes | Provides a relaxed, upright riding position, enhancing comfort and visibility but reducing aerodynamic efficiency. |
Handlebar rise affects riding comfort and performance differently:
- Road Cycling: Low-rise handlebars are preferred for an aerodynamic position that enhances speed but may cause discomfort on long rides.
- Mountain Biking: Medium to high-rise handlebars offer better control and comfort on rough terrain. making descents and climbs easier.
- Commuting and Casual Riding: High-rise handlebars provide a comfortable. upright position that reduces back and shoulder strain and improves visibility.
- Gravel and Touring: Medium to high-rise handlebars strike a balance between comfort and control. ideal for long rides on mixed terrain.
