What Size Bench Vise Do You Need?

Start with what you clamp most

Vise size comes down to two numbers: jaw width and maximum opening. Jaw width is how much of a workpiece the jaws can grip. Maximum opening is the widest gap between the jaws, which sets the thickest piece you can hold.

Think about your most common jobs first, not the biggest job you can imagine. A larger vise is not always better. It takes up more bench, weighs more, and can be awkward for small parts.

• Small repairs, filing, light drilling, and hobby parts: smaller jaws are fine.
• Metal, pipe, and general garage work: a mid-size bench vise, often with pipe jaws and an anvil.
• Woodworking on boards, doors, and furniture parts: wide jaws and a large opening.
• Mixed use: pick the size for the larger of your two main jobs, then check that your bench can handle it.

How to measure a bench vise

Published sizes can be confusing, so know what each number means before you compare models. Always measure the same way the maker does.

Jaw width is the length of the jaw face, measured side to side across the front. Max opening is the distance between the jaws when the handle is fully backed out. Throat depth, when listed, is how far down you can drop a workpiece below the top of the jaws.

Keep in mind that a vise name can be misleading. A model marketed with a certain number in its name may list a different jaw capacity in its specs, so check the spec sheet rather than the title.

If you add wood facings to protect a finished surface, they take up some of the opening. Subtract the thickness of both facings from the number you see on the box.

Sizes from our spec comparison

Here is how several models on our spec sheet line up. Jaw widths and openings come from published specifications. Our best bench vise page ranks these and more on the same data.

Notice how jaw width and opening do not always match. The Jorgensen 41012 lists 10 inch jaws with a 13 inch opening, while the Yost M9WW lists 9 inch jaws with a 10.25 inch opening. The Wilton WVA6 lists 6 inches for both.

Match the size to your stock

For small parts and quick household tasks, jaws of 4 to 5 inches are usually plenty. The Yost LV-4 sits here with 4.5 inch jaws and a 3 inch opening. That opening is small, so it suits thin stock and small parts, not thick lumber.

For general shop work with metal and pipe, a 6 to 8 inch vise gives more room. The Wilton WVA6 lists built-in pipe jaws and an anvil, and the VEVOR KS08 lists an 8 inch jaw width and opening. These are general vises, and they suit wood less well than true woodworker's models.

For furniture and long boards, go wider. Wide jaws spread pressure and hold boards flatter. The Jorgensen 41012 and Yost M9WW are the larger woodworking options in our data, and both list quick release. The Jorgensen 41012 also lists toed-in jaws and countersunk holes for wood facings.

If woodworking is your main use, opening matters as much as jaw width. A wide jaw with a small opening still cannot hold thick stock.

Check your bench and mounting

A vise only works as well as the bench under it. Before you buy, look at how it attaches and whether your bench can take it.

Benchtop models clamp to the bench top and have a limit on how thick the bench can be. The Jorgensen 41012 lists a limit of 3 inches. Bolt-on models need holes drilled in the bench. The Wilton WVA6 bolts down through four 0.51 inch holes. Under-bench models, like the IRWIN 226361, mount to the underside.

Weight matters too. The Yost LV-4 lists 9 pounds, the Yost M9WW lists 32.07 pounds, and the VEVOR KS08 lists 40.79 pounds. A heavier vise can stay steadier under load, but it needs a sturdy, well-built bench. A light folding table will flex and rock no matter which vise you choose.

Leave room around the vise, too. You need space for the handle to swing and for long workpieces to extend past the bench edge.

A simple way to decide

Use this quick process to land on a size without overthinking it.

• Write down the thickest and widest piece you clamp regularly.
• Pick a max opening larger than your thickest piece, with extra room for wood facings.
• Choose jaw width based on the length of the board faces or parts you hold.
• Check the bench thickness limit or mounting holes against your actual bench.
• Confirm the bench can carry the vise weight without wobbling.

Safety notes

Wear eye protection when cutting, grinding, or hammering on a clamped workpiece. Metal chips and wood splinters can fly. Add hearing protection for grinding or long sawing sessions.

Keep fingers clear of the jaws and moving slide bars. Some vises include pinch-point guards, but they do not remove the risk.

Do not slide a pipe or cheater bar over the handle to get extra force. Some makers say the handle is designed to bend before the vise is damaged. Do not use a vise as a press unless the maker says it is built for that.

Mount the vise firmly and tighten the lock on any swivel base before you start. Follow the maker's manual for fasteners and bench limits.

Frequently asked questions

Is a bigger vise always better?

No. A larger vise takes up bench space, weighs more, and can feel clumsy on small parts. Choose the size that fits your usual work and your bench.

Do I need a swivel base?

Only if you often need to turn the workpiece to reach it from different angles. Our data lists swivel bases on the Wilton WVA6, the VEVOR KS08, and the Yost LV-4. Woodworker's vises in our data do not list one.

What is a toed-in jaw?

Toed-in jaws are machined so the tops close slightly before the bottoms. This helps grip a board firmly while you cut, drill, or shape it.

Can I use a metalworking vise for wood?

Yes for light jobs, but it is not ideal. General vises often have smaller openings and no provision for wood facings, so they can mark finished surfaces.
