Overwatering is from the frequency of watering, not the amount you give It’s about whether the roots have access to oxygen. When sitting in wet soil, it can’t get that, it’s suffocated. Having sufficient light, airflow, drainage, and proper pot size is important to make sure the plant won’t suffer from that. For pot size, you shouldn’t have to worry too bad about it if it’s right. It should be 1-2 inches wider than the root ball (not the foliage)
