Dr. Martens Size Chart and Fit Guide

The current official Dr. Martens approach is straightforward: start with the US size guide, expect most styles to run true to size, and remember that fit can change by silhouette. If you are between sizes, Dr. Martens says it is usually better to go a little bigger and use an insole.

How to measure before you order

On the same official size guide, Dr. Martens says to stand on paper, mark the longest toe and the heel, then measure the distance between those marks and match it to the chart. Use the kind of socks you plan to wear with the boots or shoes, because that can change the result.

Do Dr. Martens run big or true to size?

Dr. Martens says on its US size FAQ that the size of its boots, shoes, and sandals can differ between silhouettes, but that most run true to size. That is more useful than blanket advice to always size up or always size down.

Wider, narrower, and unisex fit differences

The current official guide says men's and unisex styles are the better starting point if you want a wider fit with a more rounded toe, while women's styles are the better starting point if you want a narrower, more tapered fit. That means the same numeric size can still feel different across product lines.

What to do if you are between sizes

Dr. Martens says on the size guide FAQ that it is better for the fit to be a little bigger rather than too small. Its recommendation is to use an insole in the larger size if you are between sizes.

What the current guide says about tightness and break-in

Dr. Martens says its shoes often stretch in width but not in length with wear. If there is only slight pressure on the instep, that may ease over time, but if the shoe feels very tight, the brand says you may need a larger size. That is why toe room matters more than hoping the boot will lengthen later.

Kids sizes Dr. Martens currently shows in the US store

The current US kids footwear section shows these size bands in live filters. This is useful for shopping, but it is not the same thing as a full official kids conversion chart.

Kids segment	Current US sizes shown
Newborn	1, 2, 3, 4
Infant	4, 5, 6, 7, 8, 9, 10
Toddler	7, 8, 9, 10
Junior	11, 12, 13, 1, 2, 3, 4
Youth	5, 6

Why older Dr. Martens charts can mislead you

Older size posts often flatten the brand into one rule, but the current official guide does not. It shows some half-size conversions, says most styles run true to size, and warns that fit can vary between silhouettes. If a chart you find says there are no half sizes or that every pair fits the same, treat it as outdated unless the product page confirms it.

What the chart cannot tell you on its own

Dr. Martens says some product pages also include inner length and inner width data, and many pages include fit recommendations drawn from customer reviews. So use the size chart first, then check the specific product page if you are buying a unisex last, a women's-specific silhouette, or a style with an unusual toe shape, lining, or material.

Bottom line

The best current Dr. Martens size advice is to trust the official US size guide, measure your foot, and then adjust for the silhouette you are actually buying. Most styles are meant to fit true to size, wider shoppers should look closely at men's and unisex pairs, and anyone between sizes should usually go up and add an insole. For kids, use the live size bands in the kids section unless Dr. Martens publishes a fuller current conversion chart for the exact line you need.
