A real Persian rug is knotted by hand, and the easiest place to see that is the back. Turn a corner over. If the pattern shows through, made of thousands of small separate knots in rows that aren’t quite even, a person tied it. A cloth backing, glue, a blank underside or a pattern as regular as graph paper almost always means a tufted, printed or machine-made copy.

The checks take a minute and need no tools. The fringe and the sides then confirm what the back tells you.

From across a room any rug can look right; the back, the fringe and the sides tell you how it was made.

How to tell if a rug is hand-knotted: four checks

The back. The pattern shows through as rows of small, separate knots that are not quite even.
The fringe. It comes straight out of the body of the rug as the ends of the warps, with no stitching.
The sides. They are wrapped by hand in wool, with small changes in tension along the length.
The shape and color. Slightly uneven ends and soft bands of color are normal in a knotted rug.

A rug sold as “handmade” can still be tufted or hooked, so the back is the check that matters most. Each test is explained below, with what a copy shows instead.

How it was made, and where

“Is it a real Persian rug?” is usually two questions. The first is how the rug was made: knotted by hand, one knot at a time, or produced some faster way. The second is where it was made. A rug can be hand-knotted in Persia, hand-knotted in Turkey, or machine-made anywhere in the world with a Persian design.

You can settle the first question at home. The second takes more experience. Knot type, drawing and color all help.^[1] We cover them in Persian and Turkish rugs: how to tell them apart and our guide to Persian rugs. This post sticks to the first question.

Turn it over

The back is where copies give themselves away, because nobody finishes the back of a copy to look like the back of a knotted rug. Lift a corner in good daylight and take your time.

The back of a red Tabriz rug, its palmettes and curling vines showing through in rows of small separate knots and pale weft threads — The back of a hand-knotted rug, the quickest test there is. The design comes through a little softer, built from separate knots.

What a hand-knotted back looks like

Each knot is tied around the warps, the threads that run the length of the rug.^[2] On the back, each knot shows as a small bump of color. Together those bumps draw the pattern a second time, a little blurred but clearly the same design. The rows are not perfectly straight. A row drifts, a knot leans, a color change arrives one knot early. Between the rows you can often see the thin cross threads, called wefts, that lock each row in place.^[2]

Now fold the rug face out across its width. The pile parts in a line, and you can see the base of each tuft wrapped around the warps. That view is very hard to fake.

What a hand-tufted back looks like

A tufted rug is made with a hand-held tool that punches loops of yarn through a stretched cloth. The loops are fixed with a coat of latex glue, and a second cloth is glued over the back to hide it.^[3] So the back is plain fabric, often like canvas, with no pattern at all. If the cloth has lifted at a corner, you will see the glue and the rows of loops underneath.

Tufted rugs are often sold as “handmade,” which is true only because a person held the tool. What happens to that glue over the years is covered in why hand-knotted rugs outlast machine-made ones.

What a machine-made back looks like

A rug made on a power loom can show its pattern on the back too, which is why it fools people. The giveaway is how regular it is. Every row is ruler straight and every dot of color is the same size and shape. A motif at one end matches the same motif at the other end exactly. The rug usually feels stiffer and flatter than a knotted rug of the same thickness.

What a printed rug looks like

The cheapest copies are printed, with the pattern applied to the surface of a plain pile. The back is blank. Part the pile and look at the base of the fibers. On a printed rug the color often fades toward the base, and outlines look fuzzy where the ink spread. On a knotted rug each tuft is one dyed yarn, the same color from tip to knot, apart from any sun fading at the very tips.

Check the fringe

On a hand-knotted rug, the fringe is the ends of the warps. These threads were stretched on the loom before the first knot was tied, and they run through the whole rug. When the rug comes off the loom, the loose ends are left as fringe, often after a narrow flat-woven band that holds the last rows of knots.^[2] Look where the fringe meets the pile. If the threads come straight out of the body of the rug, you are looking at the warp.

End of a navy and red Persian Hamedan rug on dark walnut, short loose white warp threads coming straight out of a narrow woven band — The end of a Hamedan, 8 feet 10 inches by 11 feet 3 inches. The white fringe comes straight out of the rug past a narrow woven band, so it is the warp itself and nothing is stitched on.

On most machine-made and tufted rugs, the fringe is a separate strip sewn or glued along the ends. Fold the end over and you will usually find the stitching. A sewn-on fringe almost always means the rug is not hand-knotted.

A warp fringe doesn’t prove the opposite, though. Some machine-made rugs have a fringe that is part of the weave, so check the back as well. A missing fringe proves nothing either, because restorers sometimes turn worn warp ends under and bind them.

On our rugs the fringe is short, about an inch, and it is still the warp. Our post on rug fringe explains why cutting it off is a bad idea.

Check the sides

The long edges of a hand-knotted rug are finished by hand. Wool is wrapped around the outermost warps down the full length of the rug. At a glance the wrapping looks even. Up close you will see small changes in tension and a line that wanders a little. On an old rug, some stretches may have been rewrapped in a slightly different shade. That is ordinary upkeep, and it is part of what the specialists we work with do when they wash and restore a rug.

Machine-made and tufted rugs usually have a machine-stitched binding or a fabric tape along the sides. It is perfectly regular, and it sits on top of the edge instead of being part of it.

Small irregularities are a good sign

Hand-knotted rugs are rarely perfect rectangles. One end is often a little wider than the other, and a side can have a gentle wave. A medallion may be a few knots taller than its twin, or a border may squeeze a motif to get around a corner. The color can also shift across the rug in soft bands, called abrash, where the weaver started a new batch of dyed wool.^[4] Our post on natural dyes explains those bands. All of this is normal in a rug that one person made by hand over many months.

The two medallions look alike but are not identical, and the small bird figures near each end are placed by eye.

A machine-made rug is the opposite. The four corners match exactly and the color is the same from end to end. The rug also measures exactly what the label says, such as 5 by 8, 8 by 10 or 9 by 12 feet. A vintage hand-knotted rug rarely lands on a standard retail size, which is why our listings give the measured size in feet, inches and centimeters. If a “vintage Persian” is sold as exactly 8 by 10 feet, ask for the real measurement.

A very neat rug can still be hand-knotted

Being regular doesn’t prove a machine made it. City workshops wove from a drawing on graph paper, one square for each knot, and a good workshop rug can look almost engineered from across the room.^[5] The back still tells you. The knots are tiny, but they are separate knots, and the rows carry the small unevenness of human hands.

Words on the label to read carefully

Much of the confusion comes from the wording on labels and listings.

“Persian design,” “Persian style” or “Oriental.” These words describe the pattern only. A machine-made synthetic rug can honestly carry all three. Our post on oriental rug vs Persian rug explains what the wider word means.
“Handmade” or “hand-loomed.” Tufted and hooked rugs can use these words too. Only “hand-knotted” means knots tied one at a time.
“Silk,” “art silk” or “bamboo silk.” At a modest price this usually means viscose, which looks like silk in a photograph and wears very differently on a floor.^[6] Our guide to rug fibers explains the difference.
A knot count. It tells you how fine a rug is, and nothing about whether it is real. What determines the cost of a rug covers what a higher knot count buys.

When you are buying online

You can’t fold back a corner through a screen, so ask for photographs that let you do the same checks. You want the back, the fringe where it meets the pile, and a side edge. A seller who knows a rug is hand-knotted has no reason to refuse. Ask for the measured size too, and for the age as a range rather than a single year. Antique vs vintage rugs explains why ages are estimates.

Every rug we sell is hand-knotted wool on a cotton foundation, Persian or Turkish, about fifty years old, and washed and restored before it is photographed. Our authenticity page sets out what we can tell you about a rug and what nobody can know for sure. If you want to see the back of a particular rug before you decide, ask us for a photograph. The Persian collection and our Kashan rugs are good places to practice these checks, one listing at a time.
