How to Measure a
Vertical Jump
Tandem’s Vertical Challenger is the perfect tool to meas-
ure and improve vertical jump. It is adjustable from 4 to 12
feet to accommodate athletes of any size or skill level.
1. Using the height settings guide (guide can be found
on sticker on base of unit), set the device to the
proper range to obtain a standing reach measure-
ment. Height ranges are in two foot increments.
2. Have the athlete stand under the device and reach
as high as possible, keeping feet at on the ground.
Point the nger tips to move the highest vein
reached and record this value as standing reach.
3. Reset the veins and have the athlete jump from a
stationary position or take a few steps back and
jump as high as possible. Record the highest vein
reached as the jump reach. Be sure to reset the veins
after each jump.
4. Subtract the standing reach from the jump reach to
determine vertical jump score.
User tip: If the athlete’s standing or jump reach falls out-
side of the height setting range and no measurement can
be obtained, then the unit will need to be adjusted to the
next height setting range so a standing or jump reach can
be measured.
Other uses for the Vertical Challenger:
• Measure the vertical jump from a standing position
with no step approach.
• Use as a conditioning tool with repetitive speed jumps.
• Use to increase vertical jump with maximum station-
ary jumps.
• Use to measure an individual’s height.
