Can I use this calculator if I only know my waist measurement in centimeters?

Yes, the Belt Length Calculator supports both inches and centimeters as input units, and it outputs labeled size conversions across US, EU, UK, and other international standards regardless of the unit entered.

What does the hole range output tell me about belt fit?

The hole range shows the span from the shortest to the longest hole on the belt, helping you understand how much adjustment space is available beyond the recommended middle hole.

Is the recommended middle-hole length the exact size I should order?

The middle-hole length is a starting point; the tool notes that two holes shorter and two longer provide about two inches of play, so you can adjust based on your preferred belt fit.

Does the calculator account for different belt widths when fitting pants loops?

Yes, the tool provides width tips: jeans typically use a 1.5 in / 38 mm belt, while dress pants typically use a 1.25 in / 32 mm belt, to help match the belt to your pants loops.
