Simms Wader Size Chart: How to Measure and Pick a Size

The Simms wader size chart is a set of tables on Simms' own size and fit guide, and you use it by taking four measurements (chest or largest girth, waist, hips and inseam), then matching your girth first, your inseam second and your stockingfoot boot size third. This page does not copy the chart, because sizes and models change. It explains how Simms says to measure, what the fit labels mean, what to do when you land between sizes, and how the men's, women's and kids' charts are split, with a link to the maker's chart for the pair you are buying.

Short answer

Measure yourself, then use the chart for the exact Simms model, not a chart from a different maker and not a chart from a different Simms product. The measurements are chest, waist, hips and inseam. Simms says to start with your largest girth, then match inseam, then choose the boot size. The chart itself lives on the Simms size and fit guide, and I am not reproducing it here: numbers change with models, and a stale table is worse than none.

Brand background and the Simms products we track on Amazon US are on the Simms brand page. For the general version of this guide, covering all makers, see the wader size chart.

The four measurements

Use a soft tape and wear thin layers. Stand naturally and keep the tape level. These are the points Simms names:

The largest of the girth measurements is the one that sets your size on the chart. That surprises people, who expect the chest to rule. A person with a narrow chest and wide hips should start from the hips. (The Seam would like it known that it does not care which of your measurements was the largest, only that it was taken seriously.) Men's wading pants are the exception, because pants have no bib, so they use waist.

What the labels mean

So King and Full are about build, not height. If the standard size is right for your legs and tight through the body, that is the signal to read the King or Full row. As with all makers, read the chart for the model rather than trusting the word. Our general guide notes that no two makers define these labels in the same way.

Between sizes

Simms gives clear rules for the in-between case:

SITKA says the same about bootfoot waders from its own point of view: a little extra room fits thick socks, and a tight boot compresses socks and leaves feet cold. That is a different maker, but the logic is the same.

Boots and the stockingfoot

Stockingfoot waders end in a neoprene sock, and you buy wading boots separately. Simms says the boots need room for the stockingfoot, and the size guide has cross-reference columns to match your regular street shoe size to the boot size. Women's boots have their own cross-reference to the men's boot sizes. Kids' boots map to kids' street shoe sizes. Not every boot style comes in every size, so check the individual boot page.

Two Simms details that can save a mistake: bootfoot waders are made by attaching a boot size to a stockingfoot wader, and only select models can be converted, and some sizes are only available through the Simms Custom Wader Shop. If the standard sizes don't fit your build, ask about that route. See our stockingfoot waders and bootfoot waders pages for the difference between the two foot types, and the wading boots section for boots from other makers.

What to wear while you measure

Simms says not to wear jeans or sweatpants under waders, because they are abrasive and hold moisture. It recommends synthetic or wool layers. Measure and try on in the layers you will wear: a fit that works over a T-shirt will not work over a fleece. If you plan to wade in cold water, try the waders with the thick layers on.

Men's, women's and kids' charts

Simms splits its charts. Stockingfoot waders, wading boots, footwear, tops, bottoms, bibs and pants each have separate men's and women's charts, and kids have their own. The bootfoot wader chart lists only men's sizes. Socks share one table with men's and women's columns, and gloves and hats have a single chart. So if you are shopping for a woman's pair, check you are on the women's chart before you read a number. For a child, use the kids' chart, keep the child in shallow water with an adult close by, and see our youth wader size chart guide.

After you pick a size

A fit check is worth more than any chart. Try the waders on with your layers and do a deep knee bend, sit down and step up on a chair. You should not feel pulling or binding. SITKA says the same, and so does the general advice in our wader size chart guide.

If the size works, the waders page shows what the maker states for each pair, and the Simms waders warranty guide explains what happens if a pair leaks. If you are still choosing between types, read our types of waders guide.

Questions people ask

How do I find my Simms wader size?

Per Simms' size and fit guide, measure your chest at the widest part, your waist at the smallest part (usually just above the belly button), your hips at the fullest part, and your inseam from the bottom of the crotch to the floor. Start with your largest girth measurement, match inseam next, and then pick the stockingfoot boot size. Simms also recommends the wader size finder on each product page.

What do King and Full mean in Simms waders?

On the page I read, Simms does not define King (men's) or Full (women's) in text. In its charts, those sizes sit at the same inseam as the standard size with a larger girth. So the label points to a fuller build, and the numbers on the chart for your model are what decide.

What if I'm between sizes in Simms waders?

For bootfoot waders, Simms says there are no half sizes, and if you are between sizes you should size up. For wading boots, Simms says most people fall between their street shoe size and one size larger, and for half sizes it also says to size up. For stockingfoot waders, the rule is to match girth first and then inseam.

Do Simms boots run big or small?

I can't answer that, and I won't guess. Simms says boots need room for the neoprene stockingfoot, and it gives a cross-reference column that matches your street shoe size to a boot size. Use that column, not a rule of thumb. Not every boot style comes in every size, so check the product page.

Does Simms have a women's wader size chart?

Yes. Simms publishes separate men's and women's charts for stockingfoot waders, wading boots, footwear, tops, bottoms, bibs and pants, and kids have their own charts. The bootfoot wader chart on the page lists only men's sizes. Women's labels use Short, Regular and Tall, which Simms ties to height ranges.
