why horses are measured in hands;
The origin of measuring a horse this way is very old, but easy to understand. In days long ago people did not have the common measuring devices (like tape measures, etc.) that we do today. To measure a horse, they used what was handy:Their hands. At various times in history and in different locales a "hand" was defined as the width of a person's hand using the fingers only, the width of a person's hand using the fingers and the thumb, the height of a clenched fist, and possibly others. Somewhere along the way, the measuring unit of a hand was standardized to mean four inches. Though the origins are ancient, a hand is still the unit of measurement for horses that modern horse owners use today.
