That calls for a 4/3 mm full suit, with boots optional. Wind, air temperature and how long you stay in all matter too, so if you run cold, tick the box to move down one band sooner.
How the wetsuit calculator works
WetsuitSizeCalc compares your height and weight with each size in a generic men’s or women’s chart. A size scores zero when you are inside both its height and weight range; otherwise it scores the inches you are outside the height range plus the pounds outside the weight range divided by five. The lowest score wins, with ties going to the size whose range middles are closest to you, and the runner-up is shown as an alternative. For thickness it takes the water temperature, subtracts 6 °F if you dive and 4 °F if you run cold, and looks it up in the temperature chart.

Frequently asked questions
What thickness wetsuit for 60 degree water?
A 3/2 mm full suit is the usual choice for 60–64 °F (16–18 °C).
Is a thicker wetsuit always better?
No. Thicker neoprene is warmer but stiffer and more tiring to paddle or swim in, so match it to the water.
When do I need a hood?
Usually below about 50 °F (10 °C), or earlier if you duck-dive a lot or feel the cold.
Is WetsuitSizeCalc free?
Yes, with no sign-up or ads, and your measurements stay in your browser.
Is this chart the same for every brand?
No. It is a typical generic chart. Brands vary, so confirm with the maker’s chart, and try a suit on if you can.
