Piano Footrest or Pedal Extender? Measure Your Child’s Setup

A child can reach the keys comfortably and still have nowhere to put their feet. Lowering the bench until the feet touch the floor may then leave the arms too low for the keyboard. A foot support solves one part of that setup; a pedal extender adds a way to operate the piano’s pedals.

Set the playing position before measuring the gap

Ask the teacher to establish the bench height and distance with the child at the actual keyboard. Faber’s Primer Teacher Guide treats seating height, arm position and foot support together, and identifies foot stands and pedal extensions as possible aids. It does not give one footrest height for every child.

You need: a tape measure, the instrument’s model name and pedal information, a pencil, and an adult to make adjustments. No app or paid subscription is required. If the bench cannot reach the agreed position securely, resolve that first; our adjustable-bench guide compares actual adjustment ranges.

With the child seated comfortably, identify the level where both feet can rest without reaching down with the toes or lifting the knees unnecessarily. Measure from the floor to that proposed support surface. A teacher can help judge this position using a secure existing support. Avoid a loose stack of books that can slide during the check.

The two views below keep the vertical measurement separate from the space the unit occupies. The sides and adjustment handles may extend beyond the surface that supports the feet.

Copy this sheet into a note and send it with photographs of the pedal area when asking a seller to confirm fit:

Required pedals: damper / soft / sostenutoThe device must release completely without catching the case or leaving a pedal partly down.

Three designs to compare against those measurements

A higher price does not resolve a mismatch between the platform and the child. The following examples show different adjustment approaches. Prices are supplier references checked 20 September 2026 in USD, before tax and shipping; they are not Amazon prices. Stock limitations are noted beside the affected product.

None of these designs requires software or a subscription. Pads, buffers and other wearing parts may eventually need replacement; those variable maintenance costs are not priced here. A suitable existing footrest can also remain the no-purchase option if the teacher confirms its height and stability.

A digital piano needs its own compatibility check

Digital pianos use pedal shapes and mountings that can differ substantially from acoustic instruments. Genepis describes this problem in its Dezipeta digital-pedal design, which uses a dedicated attachment arrangement. That is a reason to send a model number and measurements, not to assume that every extension will work.

A loose sustain pedal on a cable raises another question: what stops the pedal and foot support from moving relative to one another? A stand’s cross-brace may also occupy the exact space a combined extender needs. Do not clamp an accessory onto an unsuitable plastic housing or improvise a raised stack beneath a pedal.

If the pedal itself is unreliable, address that separately using the digital sustain-pedal guide. An extender changes reach and mechanical operation; it does not repair polarity, socket or half-pedal compatibility.

Check the fitted setup before the return window closes

1. An adult assembles and adjusts it. Follow the model’s instructions, keep fingers away from springs and moving mechanisms, and check every required pad or buffer. Do not use the footrest as a step for climbing onto the bench.
2. Check the floor contact. All intended feet should sit securely. Stop if the unit rocks, slides or obstructs the bench. Soft carpet can change how it settles.
3. Confirm the child’s playing position. Hands should reach the keys from the agreed bench setting while both feet have support. The child should not need to perch forward to find the raised pedal.
4. Listen through full press and release. Test a few isolated notes with the teacher, checking that sustain starts and clears as intended. A mechanism that holds the pedal slightly down needs adjustment before practice.
5. Record the working setup. Note the bench and platform settings, lift position and date. Recheck as the child grows and whenever a different piano is used.

Once the fit works, move on to short, deliberate pedalling exercises. Take the same equipment to a recital soundcheck when permitted: a setting that works at home may need adjusting around a different instrument’s pedals.
