Saddle height for toddler's balance bike
They grow so fast it really doesn't matter, but if the kid looks too low then they are, so go up a bit.

Rider should be able to stand over the seat with both feet on the ground.

While some balance bikes have bike seats with clamps like this, they're in the minority for cost and weight reasons.


This wooden frame is far more common and much lighter for the child to manage.

Notice the seat-pole (plank?) only has two visible holes, for a total of only three seat positions.

Don't overthink this, just be an encouraging parent :)
