Is the Difference Between 400cc and 440cc Noticeable?

Thank you for your question. The choice of the implant size is difficult for women planning on having a breast augmentation. For many women, the choice is narrowed to a narrow range, and choosing can be stressful.

There is not much difference between the 400cc implant and the 440cc implant. Most people are unable to see a difference of 40cc afterwards. Keep in mind that 40cc is the equivalent of roughly 3 tablespoons of fluid - not that much. 

While it is impossible to select an implant for you without an examination, I would suggest selecting between the 2 based on your chest width. Pick an implant with a width that matches your chest width. If both sizes are close, and there is only a few millimeter difference between the 2, then either will work. Keep in mind that it is rare for women to wish that they went smaller afterwards and not uncommon to wish that they were just a bit larger.

Either way, best of luck with your augment.

In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection.
Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.

The size of the implant depends on its diameter and shape. Comparing two different implants of the same profile or shape the increasing size is only 3 mm. larger. This is not a very large difference

You have been given good information from the other posts.  I see you are 5'8" and with this height you should easily be able to handle 440 cc's.  No one will be able to tell this small size difference except you.  You should choose the size you think will fit your goals.

Best Wishes

Choose the 440 if you are concerned about being too small after surgery, choose 400 if you are afraid of ending up too big. Both are close enough in size to be similar in how natural they look.
