Traditional Practice and Community
Iyer (Smartha) Brahmins: Usually prefer the 9-yard Madisar saree for rituals and traditional occasions.
Iyengar Brahmins: Typically use the 10-yard Madisar saree for the same purposes.
Physical Comfort
People who are taller or prefer a longer drape may opt for the 10-yard saree, as it allows more fabric to comfortably cover and wrap the body.
Petite individuals often find the 9-yard option fits better and is less bulky.
Ease of Wearing (Especially Readymade)
With readymade Madisar sarees, both 9-yard and 10-yard versions are easier to wear compared to traditional unstitched forms. Your choice should still consider tradition and comfort, but the readymade version simplifies the draping process for both lengths.
