ISIZE can refer to either a software used for design (iSIZE) or European car seat safety regulations (I-Size).   

iSIZE (software)

iSize is a tool for data-driven design that uses a database of body measurements from over 100,000 individuals. It’s used by automotive manufacturers, apparel makers, aerospace, ergonomics researchers and more. Learn about iSize here. 

In addition to full-body anthropometric measurements, iSize also includes specialized data pools for specific body regions, such as detailed hand and finger measurement datasets. These datasets support highly precise ergonomic and product design applications across industries.

I-Size (EU safety regulation)

I-Size is also the name for European Union safety regulation for child car seats (ECE R129 or UN R129) that was introduced in 2013. Learn more about I-size here.
