If larger pieces of leather are to be measured, the use of a micro thickness gauge or laser scanner may be a better option. This is because these devices can measure large areas of leather in a shorter period of time and can provide greater precision and accuracy.
Miniature thickness gauges usually have a mobile stand and sliding table on which larger leather samples can easily be placed for measurement. Laser scanners, on the other hand, can scan large areas of leather and then use computer software to generate an image of the leather's thickness.
Of course, the use of each of these devices requires appropriate skills and experience. If you are unfamiliar with the use of these devices, it is best to seek professional advice or attend a relevant training course before using them.
