Can I buy a larger cuff for my existing monitor?

Possibly — Omron and A&D sell XL cuffs compatible with specific models. Check the manufacturer's compatibility list before purchasing. Third-party cuffs may affect accuracy.

Are wrist monitors a good alternative for large arms?

Wrist monitors avoid the cuff-size issue entirely but are inherently less accurate. If your arm exceeds available cuff sizes, a validated wrist monitor with positioning guidance is a reasonable alternative.
