I chose an implant 2cm less than my BWD. Is that a bad idea?

Good day! For your guidance, here is a list of generalized breast implant sizing for most patients:·  32A to 32C needs about 250-275cc·  34A to 34C needs about 300-350cc
·  36A to 36C needs about 350-400cc  
It is best to find a size in proportion with your whole body. Contact your surgeon and discuss realistic goals and expectations when deciding which implants are the best for you. Best of luck! #RealSelf100

This measurement is only a very crude guideline to help the plastic surgeon understand what the final appearance of an augmentation might be. In many situations, it is absolutely appropriate to be 2 cm under this diameter or even over this diameter. Your board-certified plastic surgeon would assist you in finding the appropriate implant to match your expectations. These numbers are very crude guidelines.

Your choice of size really needs to be discussed carefully with your surgeon. Advise from these kind of websites should always be done with caution. That being said, and after using the Ideal Implant for the past two years, I have found that it gives a lot of projection, especially at the larger fill volumes. They most closely resemble high profile implants, which are typically more narrow. The 240cc implant is rather small. So I would be concerned that unless you are extremely petite it will not fill your breast out as well and possibly leave you with a rounder look. Talk to your surgeon.

It is never wrong to use an implant that has a base width less than the width of your breast as long as you are happy with the size. The base width of the breast limits the size that you can increase to without looking unnatural- so with a sizing appointment we typically use the base width of your existing breast to determine the largest implant that you could use that would still look natural.  It is always fine to choose a smaller implant, if you are happy with the size.  Good luck and I hope this helps!

Thank you for your question. Typically, I advise patients to choose the volume that they desire and are happy with. A wider implant is not necessary to give you the look you are looking for. Be sure to discuss these questions with your plastic surgeon. Good luck with your upcoming procedure. 

If you are happy with the volume you selected, that is the most important decision.  You do not want to be larger just to have a wider implant.  Your surgeon should be able to position the implant to maximize its width on your chest wall.
