 The phrase "Retaining Ring" is sort of vague and refers broadly over several different types of retaining fasteners. Some names used include: snap rings, wire rings, circlips, lock rings, retainer clips, retainer rings among others. For our purposes,  Internal or External are the main words to remember since the rings are machined different for both types of use. Rings for bores are referred to as internal retaining rings, because the ring fits inside a hole (or bore). Similarly rings that fit over shafts are referred to as external retaining rings, because the are installed on the outside (or external) side of a shaft. \\
+Choosing what size retaining ring to buy can be challenging with all the different types and material construction. Mainly, you choose a ring based on the diameter of the housing or shaft. The groove sizes are also shown below but, in general, the piece you are working on should be sized to standard groove dimensions. However, there may be instances where special considerations were made from standards. In addition, retaining rings are made to many standards such as inch, DIN, ANSI METRIC, and JIS.
+  * Decide whether the ring installation is for internal or external applications. This determines ring sizing also.
+  * Measure the shaft (external) or bore (internal) and choose the ring sized accordingly.
+  * Be sure to measure the groove diameter also to make sure that ring will sit properly in it. \\ The ring should be snug but too tight and it will stretch beyond what it was made to handle. \\ Some rings are made for shallow grooves and some are made for deeper grooves. \\ Circlips that wrap around the shaft (axial) require less groove depth than "C" or "E" clips (radial).
+  * Most rings have tolerances for installation depending on what size and type of ring it is. \\ You can download the full PDFs of the charts below or go to their websites to see all the specs.
 ====== External Circlips ======
-External Snap rings are axial retaining rings and are installed into a groove in a shaft or bore along an axis center point. The rings have lugs and lug holes that are used for installation. Once installed, they contact virtually the entire groove. They transmit loads into the groove wall around most of the groove circumference, which lets them withstand significant thrust loadings.

-External retaining rings are sized more narrow in the charts than internal rings due to them being spec'd by their inside diameter and meant to expand onto a groove on a shaft. \\

 So comparing, measuring or ordering needs to be done in kind. \\
