Getting a bike from Giant for your child but unsure about their ideal size?
The tables below are the latest (year 2023) sizing chart vs height from Giant.
How to determine the ideal Giant size.
The standover height is the most accurate predictor of the ideal bike size. Here’s how to do it.
- Measure your child’s inseam. It’s the distance from their crotch to the ground with their regular pants and shoes on.
- Subtract 3.8cm (1.5″) from the inseam measurement to get your Child’s Standover Height.
- Child’s Standover Height = Inseam – 3.8cm (1.5″)
- Compare your Child’s Standover Height against the tables below for the preferred bike mode.
- The ideal bike size should have a Bike Standover Height less than the Child’s Standover Height.
