Caliper Dimensions
Various inside caliper dimensions are used by manufacturers today. 
Some of the units you will find measure 9.8 x 4.8 x 2.6 inches. However, there are also some inside calipers with sizes of 8 x 6 x 2, 10 x 5 x 3 and 7 x 5 x 2 inches.
Inside Caliper Facts
The inside caliper is a measuring device. Specifically, it is used for determining an object’s inner dimensions. A good example would be the inner diameter of a pipe. They can also be used to gauge the internal size of other objects. This makes the tool very useful, hence its availability in stores that sell measuring devices.
While they can be purchased in stores, some can be ordered from the maker too. There are also some manufacturers that sell custom made calipers. These devices can be utilized in special environments and settings. For example, there are calipers for use in operating rooms and microscopes. These are available in various caliper dimensions.
Design
A pair of inside calipers is comprised of a pair of arms which are curved. The curves project outwards. To perform a measurement, the tool is placed in the object to be measured.
Adjustments to the arms will be made until their ends make contact with the opening on the sides. This will allow the inside caliper to read the measurements. Some inside calipers come with locking and adjusting screws. This will permit you to take off the caliper from the object.
Accuracy and Precision
Inside calipers are often employed by machinists. It is also used by those that require specific measurements and those who function in limited tolerances. Scientists and sports car designers are among those who use these tools. The reason is simple: the slightest deviation from the real figure could spell trouble.
Other Features
Some inside calipers are fitted with padded arms. These will keep the arms from scratching the object. Many also have non-reactionary materials so they can be utilized in corrosive settings.
Considerations
Before you buy the tool, determine what measuring system you intend to use. This will make it easier to use the device. Otherwise, you will have to convert the figure, which can take a lot of time.
You also have to think about the caliper dimensions. You must try to relate this with the object’s size that will be measured. You need to make sure that the object will fit in. You must also determine the setting the tool will be used at as well.
