Is it lite or light for weight?

For weight, use “light.” “Light” means “not heavy.” For example, “This box is big but very light.”

“Lite” means the diet version of something (e.g., “lite soda”) or the less complex version of something (e.g., “the lite edition of the software”). It should only be used in informal writing.
