Best Woks for Induction Cooktops: Flat Base Sizes Compared

The best wok for an induction cooktop is a flat-bottomed one with a magnetic base that is close to the size of your cooktop’s coil. Among the woks whose makers publish enough detail to compare, the Made In carbon steel wok (5.5-inch flat base, 13.5 inches across) is the best all-round choice, the Lodge cast iron wok is the budget pick if you can handle the weight, and the All-Clad D3 Stainless 14-inch wok is the low-maintenance choice if you want to spend more. If you want a true round-bottom wok on induction, you need a different appliance: a concave induction wok burner.

Almost every “induction wok” page lists the overall diameter and stops there. On induction the number that matters more is the flat-base diameter, because the coil only heats the part of the pan that sits over it. A reader asked us to add that measurement, so it is the centerpiece of this page. Most makers do not publish it. Where they do, it is in the table. Where they don’t, the table says “not published.”

People search for this as “induction wok,” “induction ready wok” and “wok for induction cooktop.” The answers below cover all of those.

Flat base versus overall diameter

All sizes in inches. “Not published” means the manufacturer’s own page did not state the figure. Figures are the maker’s unless noted.

Only two products state the flat base outright, and both land at 5.5 inches. That matters: a 5.5-inch base is a modest match for a coil in many portable cooktops and can be well under the coil in a larger built-in burner (more on that below). For the other woks, ask the maker or measure before you buy.

Construction, induction claim and warranty

A missing induction statement does not mean a carbon steel wok won’t work. Carbon steel is magnetic, so a flat-bottomed one normally will. It does mean the maker hasn’t promised it, which is why we flag it.

Concave induction wok burners are a different category

These are the exception to the flat-bottom rule. A concave burner has a bowl-shaped glass surface with the coil curved beneath it, so a round-bottom wok sits in the dish and heats across its curve. They are sold mostly for restaurants, and they are a separate category from the flat cooktops on our portable induction cooktop page, where you’ll find the coil-size facts for flat units.

Two things stand out. The Vollrath needs a 240-volt circuit and a NEMA 6-20 plug, which most US kitchens don’t have at the counter. CookTek offers an 1,800 W model for 120 V outlets, but it is aimed at commercial kitchens and this page has not verified its consumer availability. For most home cooks, a flat-bottom wok on a good portable induction burner is the simpler route. Check current models with Vollrath or CookTek.

How we researched this

We haven’t cooked with any of these woks, and this page does not claim otherwise. We compared specifications published by the makers (Made In, Lodge, All-Clad, Tramontina, Joyce Chen, Yosukata, Vollrath, CookTek) and used retailer listings where the maker page was thin, marking those in the tables. Where a maker didn’t publish a number, we said so instead of guessing. We looked at what matters on induction: flat-base size, whether the maker states induction compatibility, material, weight, oven rating and warranty. Prices change often, so we have left them out.

Why the flat base matters on induction

Why round-bottom woks don’t work on flat glass

An induction coil heats a pan through a magnetic field that weakens quickly with distance. A round-bottom wok on a flat cooktop touches the glass at a small patch, and the rest of the bottom curves away from the coil. It heats poorly and rocks. Many cooktops also won’t start if they can’t detect enough pan on the surface. A flat base keeps the metal in contact with the glass, which is why the woks above have one.

Why a base smaller than the coil wastes power

Induction heats only the metal above the coil. If the flat base is smaller than the coil, part of the coil has nothing to heat and the energy is concentrated in a smaller area. Many cooktop manuals also state a minimum pan diameter for detection. The curved walls of a wok sit up and away from the coil, so they heat mainly by conduction from the base. Coil size varies by model, and the coil is often smaller than the ring printed on the glass. Compare the wok’s base to your cooktop’s coil, using your manual or the coil-size facts on our portable induction cooktop page. A wok with a 5.5-inch base on a burner with a much larger coil will use only part of it.

Materials compared

• Carbon steel (Made In, Yosukata, Joyce Chen, Craft Wok): light for its size, quick to respond and magnetic. It needs seasoning and can rust if left wet.
• Stainless steel clad (All-Clad, Willow & Everett, Tramontina): a magnetic stainless layer makes it induction ready. No seasoning, but food sticks more easily than on a seasoned wok. See our list of American-made stainless steel cookware.
• Cast iron (Lodge): holds heat well, but the models here weigh about 10 to 13 pounds, respond slowly and need seasoning. Lift a rough cast iron base rather than sliding it across glass. See our cast iron care guide.
• Nonstick: easy to clean, but nonstick coatings generally carry lower temperature limits than bare metal, which is a poor fit for high-heat stir-frying, and induction can heat an empty pan quickly. We left nonstick woks out of the tables because we couldn’t verify enough specs. For flat pans, see our nonstick pans for induction guide.

The woks

Made In Carbon Steel Wok

Best for cooks who want a proper carbon steel wok on induction. It is one of two woks here where the maker publishes the flat base (5.5 inches). Specs: 13.5 in across, 5 7/8 in deep, 3.5 lb, 1.5 mm, riveted stay-cool handle, made in Sweden.

• Good: stated induction compatibility, published base size, pre-seasoned, limited lifetime warranty.
• Watch out: hand wash only and needs care to prevent rust.

Lodge Cast Iron Wok

Best for budget buyers with a stable cooktop and strong wrists. Lodge sells a 14-inch model (L14W, 12.8 lb, two side handles) and the Chef Collection 12.5-inch model (LC12W, 9.72 lb, 5.5-inch flat base, long handle plus loop). Both are made in the USA. Retailers may use a different model number for the 14-inch, so check the listing.

• Good: made in USA, induction stated, oven safe, low price band ($).
• Watch out: heavy, slow to change temperature, and the 14-inch model’s base size isn’t published.

Check price on Amazon (12.5″ Chef Collection)

The 14-inch two-handle model is also on Amazon.

All-Clad D3 Stainless 14-Inch Wok

Best for buyers who want a stainless wok with a long warranty and are willing to pay for it. Specs: 14 in, 3.99 lb, tri-ply bonded with an aluminum core, riveted stainless handle, oven and broiler safe to 600°F, made in Canonsburg, Pennsylvania, limited lifetime warranty. All-Clad’s own site lists it, so it is currently sold. Lid inclusion varies by listing (the maker’s page for this model lists none, while the Amazon listing is titled “with lid”), so check what is in the box.

• Good: made in USA, induction stated, 600°F oven rating.
• Watch out: highest price band here ($$$), flat base not published, hand wash only, and stainless sticks more than seasoned carbon steel.

Willow & Everett Stainless Steel Wok

Best for buyers who want the layered stainless design at a lower price band. The retail listing gives 13 inches, 2 mm, 4 lb, an 18/8 stainless food side, an aluminum core and an 18/0 magnetic stainless base, with a domed lid and bamboo spatula included. We couldn’t confirm base size, depth, handle material, place of manufacture or warranty from a manufacturer page.

• Good: lid included, similar layered build to All-Clad, listed as induction compatible.
• Watch out: unpublished base size, and little verifiable information about where it’s made or the warranty.

Tramontina Signature 12.5-Inch Tri-Ply Wok

Best for a mid-priced stainless option with clear induction and oven statements. It has 18/10 stainless over an aluminum core, riveted handles, a 500°F oven rating, NSF certification, Brazilian manufacture and a lifetime warranty. Tramontina’s site showed it as currently unavailable when we looked, so check availability first.

Yosukata 13.5-Inch Carbon Steel Wok

Best for a low-cost, pre-seasoned carbon steel wok with a wooden handle. The retail listing gives 15 gauge and 4.1 lb; the maker describes it as flat-bottomed with a beech wood handle and manufactured in China. Neither the maker’s pages we read nor the listing gave a base size or warranty.

• Good: low price band, pre-seasoned, light.
• Watch out: wooden handle limits oven use; induction is stated by retailers but wasn’t on the maker pages we read.

Check price on Amazon

Joyce Chen 14-Inch Carbon Steel Flat Bottom Woks

Joyce Chen offers a Classic series wok (1.5 mm, birch handles) and a Professional series (1.8 mm, removable phenolic handles that are oven safe to 350°F). Neither product page states induction compatibility or a base size, so we can’t tell you how they will sit on a coil. Flat-bottomed carbon steel normally works on induction, but confirm with the maker first.

Check price at Joyce Chen.

Craft Wok

Craft Wok lists 12-inch and 14-inch flat-bottom carbon steel woks and a 13-inch pre-seasoned flat wok alongside its round-bottom range. We couldn’t retrieve the individual specification pages, so there are no figures in the tables. Ask the maker for base diameter, gauge and induction confirmation.

Buying guide

1. Find your coil size, not the marked burner. The coil is often smaller than the ring printed on the glass. Your manual or the coil-size facts on our portable cooktop page will help.
2. Ask for the base size. If the maker doesn’t publish it, email support. Aim for a base close to your coil.
3. Look for an explicit induction statement. A magnetic base is what matters, and a maker that doesn’t state it hasn’t promised it.
4. Pick a weight you can lift. The cast iron models here are 10 to 13 lb; the carbon steel and stainless ones are around 3.5 to 4 lb.
5. Check the handle. Wooden handles suit the stovetop only. Riveted metal handles and rated phenolic handles allow oven use.
6. Choose a material you’ll maintain. Carbon steel and cast iron need seasoning; stainless doesn’t.

FAQs

What is the flat portion diameter of induction woks?

A reader suggested we list it, and it is now in the first table. Only Made In (5.5 in) and Lodge’s Chef Collection 12.5-inch (5.5 in) publish it among the woks we checked. For the others it is not published, so ask the maker.

Willow & Everett wok or All-Clad wok?

This is a specs comparison, not a test. Both are tri-ply stainless with an aluminum core and a flat bottom. Willow & Everett’s listing gives 13 in, 2 mm and 4 lb, with a lid and spatula included. All-Clad is 14 in and 3.99 lb (check whether your listing includes a lid), and its maker states 600°F oven safety, manufacture in Pennsylvania and a limited lifetime warranty. For Willow & Everett we couldn’t confirm made-in or warranty. Neither publishes a flat-base diameter. All-Clad is the better documented and sits in a much higher price band; whether that is worth it depends on how much you value US manufacture, the warranty and the documented specs. It was originally left out of this page because of its price, and it is now included.

Can you use a wok on an induction cooktop?

Yes, if it has a magnetic, flat base. Round-bottom woks don’t heat properly on flat glass.

Can I use a round-bottom wok on induction?

Only on a concave induction wok burner, such as the Vollrath and CookTek units above, which are built for that shape.

Is a carbon steel wok good for induction?

Carbon steel is magnetic, so a flat-bottomed one normally works, and Made In states induction compatibility. Some other makers don’t state it.

Is a cast iron wok OK on induction?

Lodge states that it is. It is heavy and slow to respond, and a rough base can scratch glass if slid.

Is there a dishwasher-safe wok for induction?

Tramontina says its Signature stainless wok is dishwasher safe, though it recommends hand washing. All-Clad’s D3 wok is hand wash only, and carbon steel and cast iron should not go in the dishwasher.

Bottom line

For most home cooks, a flat-bottomed carbon steel wok with a base near your coil size is the best induction match. If you want less upkeep, choose a stainless tri-ply wok. If you want a round-bottom wok, buy the burner made for it.
