You are standing in front of a piece of furniture at a shop, an estate sale, or in a relative's spare room, and you want to know what it actually is. How old is it? Is it a real antique or a newer piece dressed up to look old? Is it worth anything? You do not need to be an appraiser to answer most of that. The piece keeps a record of how and when it was made, and once you know where to look, you can read it.
This is a walk-around guide. Start at the wood, move to the joints, check the hardware, place the style, then look for a name. By the time you have gone around the piece once, you will have a good sense of its age and origin. Along the way we will point to deeper guides for the two questions that come up most: is it genuine, and who made it.
1. Start with the wood
Turn the piece around and look at the back, the drawer bottoms, and any unfinished surfaces. Older furniture is built from solid wood throughout, including the parts nobody sees. If you find plywood, you are looking at a piece made no earlier than the twentieth century, because plywood did not come into wide furniture use until then. Particleboard or fiberboard pushes the date later still, generally to the mid-twentieth century and after.
Cabinetmakers also used a nicer primary wood for the show surfaces (mahogany, walnut, oak, cherry) and a cheaper secondary wood for the hidden structure like drawer sides and backboards. The secondary wood is a clue to where a piece was made, because makers used whatever was local and inexpensive. A mismatch between a fine face and a rough, honest interior is normal and expected in older work.
2. Look for wood movement
Solid wood never stops moving. Over many decades it shrinks across the grain, but not along it, and that uneven shrinkage leaves signs you can see and feel. A round tabletop or a drawer front that started life as a true circle or rectangle will often measure slightly out of round, a fraction narrower across the grain than with it. Old panels can develop a gentle cup, and joints can loosen as the wood shrinks around them.
None of that is damage. It is age doing what age does to real wood, and it is very hard to fake convincingly. A piece that is dead-square and perfectly round in every dimension, with no movement at all, is either quite young or made from a stable manufactured board rather than solid timber.
3. Read the joinery
Pull out a drawer and look at the corners where the front meets the sides. The joints there are one of the most reliable dating clues in all of furniture.
Hand-cut dovetails are few in number, a little uneven, and slightly different from one another, because a person cut each one with a saw and chisel. These point to older, pre-industrial work.
Machine-cut dovetails are uniform, evenly spaced, and identical down the row. Machine-cut joinery became common in factory furniture in the later nineteenth century, so it is a sign of the industrial era rather than the hand-craft era.
No dovetails at all, just staples, glue, or interlocking manufactured board, points to modern mass production.
Elsewhere in the piece, mortise-and-tenon joints and wooden pegs holding a frame together are marks of traditional construction. This kind of reading overlaps with proving a piece is genuine rather than a reproduction, which we cover in depth in how to tell if something is actually antique.
4. Check the hardware and the tool marks
The metal and the marks left by tools both carry dates. On unfinished interior surfaces, look at the saw marks. Straight, parallel marks come from the hand and up-and-down saws used before powered circular saws were widespread. Curved, arcing marks come from a circular saw, which came into common use in the nineteenth century, so arced marks tell you the piece is not older than that.
Fasteners tell a similar story. Irregular hand-forged nails are the oldest; rectangular, machine-cut nails belong to the nineteenth century; and round wire nails point to the very late nineteenth century onward. Screws follow the same arc, from irregular handmade screws with off-center slots and blunt ends to the uniform, pointed, machine-made screws of the modern era. Original handles and pulls, with the wear and the slightly irregular casting of old metal, add to the picture, though remember that hardware is often replaced over a long life.
5. Place the style
Now step back and look at the whole piece. Furniture styles ran in recognizable periods, each with its own vocabulary of legs, feet, proportions, and ornament. Cabriole legs and pad feet, straight and geometric lines, heavy dark carving, spare handmade simplicity, or streamlined modern curves each point to a different era. Getting the style roughly right narrows the date range and tells you what to compare against.
Style alone is not proof of age, because popular styles get reproduced in every generation, but combined with the wood and joinery it is powerful. For a period-by-period tour of the major furniture styles and how to recognize each one on sight, see our companion guide, antique furniture styles by era.
6. Hunt for a name or a mark
Finally, look for a signature. Makers and factories often stamped, branded, or labeled their work, usually where it would not show: the back panel, the inside or underside of a drawer, the underside of a tabletop, or the bottom of a chair. A maker's stamp, a paper label, or a patent date can turn an anonymous piece into an identifiable and dateable one, and a patent date in particular gives you a year the piece cannot be older than.
Marks are a whole skill of their own, and they apply to silver, pottery, and jewelry as much as furniture. Our guide to reading antique maker's marks and hallmarks covers where to look and how to interpret what you find.
Put it together
No single clue proves a piece's age on its own. The skill is in stacking them. When the solid-wood construction, the hand-cut dovetails, the straight saw marks, the period style, and an old maker's stamp all agree, you have a consistent story, and that consistency is what identification really is. When the clues disagree, when a supposedly early piece has round wire nails and plywood drawer bottoms, the disagreement is itself the answer.
Once you have a rough age and style, you can find out what the piece is worth. Our guide on how to find the value of your antiques for free shows how to check what comparable pieces have actually sold for.
See real pieces in person
The fastest way to learn to identify furniture is to handle a lot of it, and antique malls are the best classroom there is. Pull out drawers, turn things over, and compare an obvious reproduction with the real thing side by side. Search the Antique Partner directory for antique stores and malls near you and go get your hands on some furniture.
Frequently asked questions
How can I tell how old a piece of furniture is?
Read several clues together rather than trusting one. Solid wood throughout, hand-cut dovetails, straight (not arced) saw marks, irregular old nails and screws, and a period style all point to older work. Plywood, particleboard, uniform machine-cut dovetails, round wire nails, and staples point to the modern era. When the clues agree, they give you a reliable date range.
What are dovetail joints and why do they matter?
Dovetails are the interlocking, wedge-shaped joints at the corners of a drawer. Hand-cut dovetails are few, uneven, and slightly different from one another, which signals older hand craftsmanship. Machine-cut dovetails are perfectly uniform and evenly spaced, which signals later factory production. Looking at a drawer corner is one of the quickest ways to date a piece.
Where do makers usually put their mark on furniture?
Marks are almost always hidden. Check the back panel, the underside and inside of drawers, the underside of tabletops, and the bottom of chairs and case pieces. Look for a stamped or branded name, a paper label, or a patent date. A patent date is especially useful because the piece cannot be older than the year printed on it.
Does solid wood always mean a piece is antique?
No. Solid wood is a good sign, but plenty of modern furniture is also solid wood, and some genuinely old pieces use veneer over a solid core, which is legitimate traditional work. Use the wood alongside the joinery, hardware, tool marks, and style rather than on its own. It is the combination that tells you the age.
Is it antique or just a reproduction?
A good reproduction copies the style but rarely copies the construction. Reproductions tend to show modern shortcuts: machine-cut dovetails or none at all, wire nails or staples, plywood or particleboard, and wood that has not moved with age.
