Breast Implant Dimensions
Tuesday, March 2nd, 2010Breast implant sizes are determined by the projection and the diameter.
The figures will vary not just by the manufacturer, but also the type of breast implant.
Saline Breast Implants
There are many types of breast implants. The following measurements are for the smooth round types. Implants with a diameter of 9.5 cm will have a projection of 3 cm. A 10 cm diameter has a projection of 3.1 cm and a 10.6 cm will have a 3.3 cm projection. For 11 cm, its 3.4 cm; for 11.5 cm it is 3.5 and for 11.9 cm the projection is 3.6 cm.
A breast implant size of 12.3 will project 3.7 cm. 13 cm in diameter will project 3.8 cm and 13.3 cm in diameter by 3.9 cm. 4 cm is the projection of an implant with a diameter of 13.6. For 14.2 cm it is 4.1 cm; for 14.8 it is 4.2 cm. For 15 cm, the projection is 4.2 and for 15.6, 4.9 cm.
These dimensions are usually the “normal” or average. Some manufacturers come up with a “plus” size. This alters the projections of the implants. A 9.5 cm diameter will have a projection of 3.5 cm and a 10 cm diameter, a projection of 3.7 cm.
10.4 cm will project 3.8 cm; a 10.8 cm by 4. cm and 11 cm by 4.1 cm. 4.3 cm is the projection if the diameter is 11.5. If the diameter is 11.9 the projection is 4.4.
A breast implant size of 12.1 will project 4.5 cm. If it’s 12.3 cm, the projection is 4.6 cm. For 12.9 cm it is 4.8 cm. For 13 cm the projection is 4.9 cm; for 13.3 cm (5 cm) and for 13.6 cm (5.1).
For 14 cm it is 5.3 cm. For 14.5 cm the projection is 5.5. cm. For 15.2 cm it is 5.8 cm; for 15.6 cm, the projection is 5.9 cm and for 16.1 cm (6 cm).
Silicon Breast Implants
Some of the typical silicone breast implant measurements are the following. A diameter of 8.4 cm will project 3.6 cm; for 8.9 cm the projection is 3.8 cm and for 9.4 it is 4 cm. At 10.2 cm in diameter, the projection is 4.3 cm. If the breast implant size is 10.5 cm the projection is set at 4.5 cm.
At 10.9 cm, expect a projection of 4.6 cm; at 11.1 cm it will be 4.7 cm and for 11.5 cm it will be 4.8 cm. At 11.8 cm the projection goes up to 4.9 cm. At 12 cm, projection is at 5 cm.
For 12.3 cm it is 5.1 cm; for 12.5 (5.2 cm), 12.7 (5.2 cm) and at 13.2 cm, the projection is 5.4 cm. At 14 cm, the projection is 5.7 cm, 6 cm for 14.7 diameter and 6.3 if the diameter is 15.4 cm.
Variations in Size
Please remember that there are many more sizes to choose from. A saline breast implant is subdivided into many categories as do those that use silicone and other gels.
Breast implant sizes will also vary depending on the manufacturers. It is a good idea to compare the different types to see which best suits you.
