Digital bathroom scales produce a numeric readout which displays on a small screen located on the front of the scale. Mechanical bathroom scales have a needle which adjusts itself to a person's weight once the scale has been stepped on.
Mechanical bathroom scales generally have a fixed weight limit lower than that of digital scales, meaning that those exceeding a certain weight would not see an accurate depiction of their weight.
Digital bathroom scales operate using a small lithium battery, while mechanical scales do not require anything to power them.
Both digital and mechanical bathroom scales are available in virtually any color and design.
Digital scales often feature added perks, such as body fat percentage readout and user memorization. Mechanical scales are used solely to display weight.
