The best bench planes for most woodworkers are a No. 5 jack plane for general work, a No. 4 smoothing plane for final surfaces, and a No. 7 or No. 8 jointer plane when long edges or boards must be made accurately straight; the right choice depends more on sole length, blade geometry, and handling than on brand alone.

Quick picks by woodworking job
- Best all-purpose bench plane: A No. 5 jack plane, especially with a 45° blade and a second cambered iron for stock removal.
- Best smoothing bench plane: Lie-Nielsen No. 4 or Veritas Bevel-Up Smoother, depending on whether you prefer traditional frog adjustment or a low-angle bevel-up design.
- Best for jointing: Lie-Nielsen No. 7 or No. 8, or an equivalent long-soled metal plane in the 22–24-inch class.
- Best for difficult grain: A bevel-up plane with interchangeable blades, allowing a higher cutting angle such as 50° or 55°.
- Best budget route: A sound vintage Stanley Bailey No. 4 or No. 5, provided the sole, frog, adjuster, and lever cap are serviceable.
- Best for traditional wooden bench planes: A well-fitted wooden jack or jointer plane, which is light and comfortable but requires more setup skill.
Bench plane comparison
| Plane type | Typical sole length | Typical blade width | Approximate weight | Best use |
|---|---|---|---|---|
| No. 4 smoother | 9–10 in | 2 in | 4–5 lb | Final smoothing and small workpieces |
| No. 5 jack | 14 in | 2 in | 4.5–6 lb | General bench work, flattening, edge preparation |
| No. 5 1/2 fore plane | 15–16 in | 2 1/4 in | 6–8 lb | Faster flattening with more stability than a No. 5 |
| No. 6 fore plane | 18 in | 2 3/8 in | 6.5–8.5 lb | Flattening medium and large boards |
| No. 7 jointer | 22 in | 2 3/8 in | 7.5–9 lb | Jointing edges and straightening long faces |
| No. 8 jointer | 24 in | 2 5/8 in | 9–11 lb | Maximum stability on long boards and edges |
These are representative dimensions rather than universal standards. Individual manufacturers vary, and a bevel-up plane may be shorter or lighter than a traditional plane while still performing the same role.
Which size should you buy?
No. 4: the smoothing specialist
A No. 4 bench plane has a short sole that follows local contours rather than averaging them over a long board. That makes it agile around panels, cabinet parts, and narrow stock. It is not the best tool for flattening a twisted tabletop: its short sole can follow the twist and remove material unevenly.
For smoothing, fit the blade with a nearly straight edge and only a slight corner relief. A mouth opening around 0.004–0.008 inch is suitable for fine shavings, although exact settings depend on grain and blade geometry. Lie-Nielsen’s No. 4 is a premium traditional-style option with a ductile iron body and thick A2 blade; a vintage Stanley No. 4 offers much of the same format at a lower general market cost when restored properly.
No. 5: the best first bench plane
The No. 5 jack plane is the most versatile single bench plane. Its 14-inch sole is long enough to bridge modest hollows but short enough to handle comfortably. With a cambered blade, it removes high spots quickly; with a straighter blade and a tighter mouth, it can prepare a surface for final smoothing.
A typical No. 5 blade is about 2 inches wide. Set the cutting edge with a camber of roughly 1/16 inch for general stock removal, or use a second iron with a nearly straight edge for finer work. This two-blade approach costs more than one universal setup, but it avoids repeatedly changing the edge geometry.
No. 5 1/2: more mass and control
The 5 1/2 bench plane, often called a fore plane, is about an inch or two longer than a No. 5 and uses a wider blade, commonly around 2 1/4 inches. The extra mass helps it maintain momentum through wide or hard timber, while the longer sole gives more control during flattening.
Choose a 5 1/2 over a No. 5 if you regularly prepare furniture-sized boards and do not mind a heavier tool. It is less nimble for small parts and can become tiring during extended overhead or vertical work.
No. 7 and No. 8: for jointing, not merely smoothing
A No. 7 jointer plane, around 22 inches long, is the most practical long bench plane for many workshops. Its sole bridges dips, so repeated strokes can produce a straighter edge than a short plane. A No. 8 adds roughly two inches of sole length and a wider iron, but its additional weight is noticeable.
Long does not automatically mean accurate. The sole must be flat enough for the intended work, the blade must be free of side-to-side movement, and the workpiece must be supported without flexing. A No. 7 is usually the better choice for a small shop; select a No. 8 when you routinely joint long, wide boards or value maximum momentum.
Blade steel and cutting angle
Common premium bench-plane blades use A2, O1, or high-carbon tool steels. O1 is relatively easy to sharpen and gives a keen edge, but it may need more frequent honing. A2 generally holds an edge well and is widely used in modern premium planes, though it can take more effort to sharpen. PM-V11, used by Veritas in several blades, is a powdered-metal steel designed for high wear resistance and good edge durability.
Steel alone does not determine performance. A well-sharpened O1 blade in a rigid plane can outperform a neglected premium blade. For ordinary hardwood, begin around a 25° primary bevel with a 5° microbevel, producing a 30° cutting bevel on many traditional planes. Bevel-up planes alter the effective cutting angle by adding the blade bevel to the bed angle. A 12° bed with a 25° bevel produces approximately a 37° effective angle; a 50° bevel on the same plane produces approximately 62°, which can reduce tear-out in difficult grain.
Traditional versus bevel-up adjustment
Traditional Stanley-pattern planes place the frog beneath the blade. Their familiar depth adjuster, lateral lever, and frog adjustment provide a broad range of setup, but removing and replacing the blade can disturb settings. Lie-Nielsen and Clifton make refined traditional-style planes, while restored Stanley Bailey planes remain widely available.
Bevel-up planes use a fixed low-angle bed and change performance through different blade bevels. Veritas offers bevel-up jack, jointer, smoother, and panel-plane designs with adjustable mouths on many models. This system is convenient if you want one body for ordinary and difficult grain, but replacement blades and specialized sharpening angles add to ownership cost.
Decision matrix: match the plane to your workshop
| Your situation | Best choice | Why |
|---|---|---|
| New woodworker buying one plane | No. 5 jack | Handles flattening, edge work, and preparation without excessive weight |
| Small shop or limited storage | No. 4 or No. 5 | Useful capability in a compact footprint |
| Frequent furniture making | No. 5 plus No. 7 | Separates general stock removal from accurate jointing |
| Large slabs and long edges | No. 7 or No. 8 | Long sole and high mass improve registration |
| Mostly final surface preparation | No. 4 smoothing plane | Responsive on small and medium panels |
| Low budget and willingness to restore tools | Vintage Stanley No. 4 or No. 5 | Low purchase cost, with time required for cleaning and setup |
| Preference for light traditional tools | Wooden jack or jointer plane | Low friction and comfortable handling, but more setup-sensitive |
Sole flatness, handling, and fit
Inspect a metal plane sole on a known-flat reference such as a thick glass plate or reliable surface plate. Mark the sole with a pencil grid and rub it against fine abrasive paper. The marks should disappear consistently across the working areas, but do not remove metal merely to achieve a mirror finish. The toe and heel can tolerate small deviations; the critical area is around the mouth and the region that contacts the work during a stroke.
Check that the blade seats firmly, the cap iron or lever cap clamps evenly, and the lateral adjustment has enough range to center the edge. The tote and front knob should allow a relaxed grip. A heavy plane that forces your wrist upward can be less productive than a lighter plane with better balance.
Setup and maintenance that affect results
- Flatten and polish the back of the blade. Only the first inch or so needs a high polish for practical honing; the rest should be clean and free of burrs.
- Establish a consistent bevel. A honing guide can help beginners repeat the angle, while freehand sharpening is faster once the motion is reliable.
- Set the blade for the job. Use a deeper, cambered projection for flattening and a fine, nearly straight projection for smoothing.
- Align the edge laterally. A blade projecting farther on one side will create a step or slanted surface.
- Wax and wipe the sole. A thin coat of paste wax reduces friction; remove dust and resin before storing the plane.
- Protect the iron from rust. Keep the tool dry, avoid leaving it on a damp bench, and apply a light corrosion inhibitor in humid conditions.
The parts that usually need attention first are the cutting edge, cap-iron mating surface, mouth area, adjuster threads, and sole finish. Do not overtighten a lever cap: excessive pressure can make depth adjustment stiff and can distort thin vintage parts. Also avoid using a smoothing plane with a heavily cambered blade; it will leave visible grooves that require extra sanding or scraping.
Final recommendation
For one best bench plane, choose a well-made No. 5 jack with a spare blade or a bevel-up jack system. Add a No. 4 when your work centers on clean final surfaces, and add a No. 7 when accurate long edges or broad faces become routine. A premium new plane offers predictable machining and less restoration, while a vintage Stanley can be excellent value if you assess its sole, frog, adjuster, and blade rather than buying by model number alone.
