Measuring and Installation

The ROT (rule-of-thumb) for the measurement of our Standing Desk Conversion Kits are:

• Grades K-2 generally will require a 19” length desk leg. This length only comes in a 1” diameter leg size. Often with these younger/shorter students, raising their desk to the highest level may be high enough to stand at (should be elbow height) and then you can get an Attachable FootFidget® and they will be all set!

• Grades 3 – 8 generally will require a 24” length desk leg extension. This length comes in both the 7/8” and 1” diameter leg size.

• Grades 9 – 12 will typically require the PORTABLE FOOTFIDGET® due to their height, weight and the fact they move from classroom to classroom during the school day.

When ordering, PLEASE take into consideration the age and heights of students who will be using the standing desks, and if it will be used by more than one student.  One size may not ‘fit’ all the various heights of students in one classroom.  Having at least 2 desks of different heights will ensure all students will be able to utilize them on a rotating basis. Take note of ‘How to measure for a standing Desk’ below!

How to Measure the Correct Diameter and Leg Length for the Conversion Kit Leg Extensions:

1. Remove the short leg extension from current desk. Measure the outside diameter of this leg. Is it 7/8” or 1”? (typically, a round leg is 1”, a leg with a  ‘groove’ or kidney shaped is 7/8” – please measure carefully).

2. Measure from the desktop to screw hole on stationary leg permanently attached to desk. Match/circle in Column A.

3. Measure the student while standing from elbow to floor. This is student’s correct desk height. Across from the circled number in Column A, match/circle  this height measurement in either Column B or C on Chart.

4. Match to top of the chart in the ‘yellow’ box – that will be the length of the replacement desk leg you need – 19” or 24” long. It is that easy!

Choose one: 1” diameter or 7/8” diameter

Measure the Outside Diameter of short Desk Leg taken off the school desk.

Typically, this is the ‘shape ’ of the tubular legs removed from the school desk, VIEWED FROM THE END. However – NOT always!
They could be a different shape so measure carefully. The difference of these two measurements does not ‘sound’ like a lot, BUT if you do not measure carefully … the leg may wobble (7/8” is too small) OR the 1” will not fit (it is too big).
Remember it is the OUTSIDE diameter. Measure carefully!


We do not sell stools at this time, however if your students are permanently at a standing desk, they will need a stool to change their positioning further during the day. To get you started we have links to several manufacturers of stools who have a reasonable price.

Remember you could also inquire where your art and science departments get their stools. They may even have a few extra they can lend you to try!

To Determine the Proper Stool Height for your student:
• Have the student stand up straight.
• Measure from the floor to the gluteal fold – this is the line where the thigh meets the buttocks.
• This will be the proper stool height.

Here are a few stool distributors:

What Researchers Are Saying

“I just love my standing desk and FootFidget®! It is so cool that I can stand up in class and not get in trouble. My FootFidget® helps me to pay attention more. I don’t know why it helps me so much, but it does. Now everyone in class wants to have a standing desk!”
