How Is Standing Reach Calculated?
Standing reach can be measured directly or estimated using body proportions. Our calculator provides both methods:
Estimated Standing Reach Formula (Using Height Only)
If you don’t have your arm length, we use the widely accepted formula:
Standing Reach = Height × 1.33
This multiplier (1.33) is based on average anatomical proportions observed in athletes and general population studies. It assumes that from your shoulders upward to your extended fingers accounts for roughly 33% of your height.
Example:
If you’re 70 inches (5’10”) tall:70 × 1.33 = 93.1 inches (≈ 7’9″)
What Is Standing Reach?
Standing reach is the vertical distance from the floor to the tip of your fingers when standing flat-footed with one arm fully extended upward. It’s one of the most important baseline measurements in sports like basketball, volleyball, and high jump. Knowing your standing reach is essential for tracking progress, estimating vertical leap, and determining your potential to dunk or block shots.
Why Use a Standing Reach Calculator?
Manually measuring standing reach can be awkward, especially without a wall chart or stadiometer. Our Standing Reach Calculator helps you estimate your reach instantly using just your height — and optionally your arm length.
Whether you’re an athlete, coach, or fitness enthusiast, this tool removes the guesswork and gives you a reliable estimate based on established body ratios. It’s also a great way to compare your reach to others in your sport or age group.
How the Standing Reach Calculator Works
There are two ways to calculate standing reach:
- Using Height Only
If you don’t know your exact arm length, the calculator multiplies your height by a standard ratio (1.33) to estimate reach. This is based on average human proportions. - Using Height + Arm Length
For a more accurate result, input your actual arm length (from shoulder to fingertip). The calculator will then sum height and arm length to get a more personalized estimate.
This calculator supports both inches and centimeters, making it perfect for users worldwide.
Who Should Use This Calculator?
- Basketball players – Determine how close you are to dunking or blocking a shot.
- Volleyball players – Track your spike or block reach.
- Coaches & trainers – Use it for scouting or developing personalized training plans.
- Fitness testers – Add it to performance tracking alongside vertical leap, wingspan, and sprint times.
- PE teachers & students – Use it for class activities or projects involving biomechanics and movement.
Related Metrics: Why Standing Reach Matters
Standing reach is often used alongside other key measurements, such as:
- Vertical Jump Height: The difference between standing reach and jump reach.
- Wingspan: Can suggest reach potential but isn’t a substitute.
- Dunk Reach / Rim Height: To dunk, your jump reach needs to exceed 120 inches (10 feet rim) by at least 6–10 inches.
Knowing your standing reach helps estimate your vertical leap without needing expensive equipment.
Compare with NBA Players and Pros
Did you know the average NBA player has a standing reach of around 8’10” to 9’3″ depending on their position? For example:
- Point guards: 7’10” – 8’6″
- Forwards: 8’6″ – 9’2″
- Centers: 9’0″ and above

Frequently Asked Questions
What’s a good standing reach for dunking?
A standing reach of around 8 feet or more gives you a strong chance, especially with a 28–32 inch vertical jump.
How do I measure standing reach manually?
Stand flat-footed against a wall and stretch one arm straight up. Mark the highest fingertip point and measure from the floor.
Does wingspan affect standing reach?
Yes, longer wingspan often increases reach but standing reach depends more on shoulder height and arm length.
