What to Do When Between Belt Sizes

What between sizes really means

Being between belt sizes means your waist sits on the edge shared by two rows of the chart, so both sizes are close to right and neither is clearly wrong. A waist of 34 inches is a good example, because it sits at the top of the band for belt size 34 and at the bottom edge of the band above it. The chart cannot settle that waist on its own, so the material, the use and the holes have to decide.

This is a common spot to land, because belt sizes step in 2 inch jumps and waists do not. A waist that falls neatly in the middle of a band is easy, but a waist that falls on a boundary needs a small judgement call. The good news is that a boundary choice is forgiving when the belt has enough holes, because either size will fasten near the middle and the difference is one hole of adjustment.

Size up when the belt is fabric or casual

Fabric and webbing belts stretch more than leather and keep stretching through the day, especially in warm weather, so a fabric belt bought in the smaller size can feel loose by the afternoon. Sizing up gives the strap room to stretch without leaving you on the tightest hole, and a casual belt has a longer tail that looks normal, so the extra length does not show.

Casual use points the same way, because a casual belt is worn with jeans or chinos where a slightly longer tail is fine and the buckle does not need to sit as neatly as it does on a suit. A work belt also suits the larger size when you are between rows, because it is worn for long days and may need to loosen as you move. Our leather versus fabric and webbing belts guide explains how each material behaves at a boundary.

Size down when the belt is leather or dress

Leather points the other way, because it gives a little with wear and then holds its shape. A leather belt bought in the smaller size will feel snug on the middle hole at first and ease into a comfortable fit after a few weeks, while the larger size will stay loose and leave a long tail. A dress belt suits the smaller size too, because the tail needs to be short under a jacket and the buckle needs to sit flat.

Think about the outfit as well as the material. A belt worn with a suit has to look neat from the front, so a short tail and a middle hole matter more than they do on jeans. If the belt is both leather and dress, the case for the smaller size is strong, and if it is both fabric and casual, the case for the larger size is strong. When the material and the outfit point in different directions, let the material decide, because stretch affects comfort all day.

Let the holes decide

Count the holes before you choose, because the hole count changes how much a boundary choice matters. A belt with five holes spaced an inch apart gives you two holes of adjustment either side of the middle, so either size will fasten near the middle and you can move a hole as your waist changes. A belt with three holes gives you only one hole either side, so the size has to be closer from the start and a boundary choice is riskier.

When you try the belt on, fasten it and look at the hole it uses. If the smaller size fastens on the middle hole and the larger size fastens one hole past the middle, both are wearable, so pick the one that matches the material guidance above. If one size fastens on the first hole and the other on the last, neither is a boundary choice, and you should re-measure before you buy.

Re-measure before you choose

A waist that lands on a boundary in every brand is worth measuring again, because the tape may be the problem rather than the chart. A tape held too loose reads larger than the waist, and a tape pulled tight reads smaller, and either error can push a waist that belongs inside a row onto its edge. Measure over the clothes you will wear with the belt, keep the tape level, and read the number twice.

If the fresh number still lands on a boundary, accept the boundary and pick by material and use, as above. A boundary is not a mistake in the chart, it is a place where two sizes overlap, and either one can fit well when the holes, the material and the outfit all point the same way. Our what to do when between pants sizes guide shows the same judgement for trousers, where the waistband meets the same edge.
