What is duck canvas?

What is duck cloth

Cotton duck (from Dutch: doek, “linen canvas”), also simply duck, sometimes duck cloth or duck canvas, commonly called “canvas” outside the textile industry, is a heavy, plain woven cotton fabric. There is also linen duck, which is less often used. Duck is used in a wide range of applications, from sneakers to use for artists’ paintings to tents to sandbags.[1] Duck fabric is woven with two yarns together in the warp and a single yarn in the weft.

Information above is from:

It is 100% cotton (sometimes cotton/synthetic blended or 100% synthetic) plain woven heavy-weight fabric. Above 10 oz/square yard (but now also include some fabric as light as 7 oz/sq.yard). The word “duck” is used to describe all kinds of canvas in North America, whereas in the rest of the world a lighter weight duck is known as “canvas” & heavy weights, used in industry, only as “duck”.

What is Duck Canvas? or canvas vs duck cloth?

Canvas and duck are terms used interchangeably and can often been confused.  Canvas is defined as an fabric that is strong and heavy having a firm hand.  Canvas  is usually used in awnings, boat covers, and outdoor furniture.  Duck on the other hand is usually spun polyester or spun cotton fabric available in a variety of weights and qualities.  Both canvas and duck are available in plain weave or basket weave.   Canvas is made from either cotton or acrylic.

There are many kinds of cotton duck cloth fabrics. They are known by names that are historically connected to them like “Army”, “Numbered”, “Belting”, “Sail”, etc.

  • Single Filled Cotton Duck Cloth: Generally light-weight, loosely woven, oxford weave cotton duck cloth, made from non-plied single yarns. The more common SF ducks weigh 7, 10 and 12 oz/square yard.
  • Numbered Cotton Duck Cloth: Heavier plain weave fabric, made with plied yarns, weighing 12 to 32 oz/square yard. #1 being 32 oz/square yard and #12 being 12 oz/square yard.  This cotton duck cloth is tight, firm cotton fabric ranging from 22″ to 150″ in width.  This is also called wide duck and the weights (numbering system) are on the inverse scale.  The weight of the fabric can be determined by subtracting the duck number from 19.  A number 8 cotton duck fabric will weigh (19-8)= 11 oz per lineal yard of 22″ width fabric.  To get the ounce per square yard, you have to prorate it to 36″ width since 1 square yard is 36″x36″.  11 oz per lineal yard(22″) is the same as 18 oz/sq. yd.  A little confusing, but that’s how he original numbering system was invented.
  • Army Cotton Duck Cloth: 10 oz & 15 oz. plain weave fabric, generally made with two ply yarns. The yarns are finer than the numbered or single fill fabrics and the weave tighter.  Army cotton duck cloth is usually firmer than single filled fabrics.  Originally used for army tents and clothes, this versatile cotton duck fabric is used in a variety of applications.
  • Belting Cotton Duck Cloth:  Heavy, plain woven, plied yarn cotton duck cloth used as conveyor belts.  Belting cotton duck has it’s greatest strength in the fill yarns.
  • Boot or Bootleg Cotton Duck Cloth:  Similar in construction to hose duck cloth, being soft and pliable and made with plied warp and fill yarns.  This cotton duck cloth was used in the leg of rubber boots and plastic reinforcements.
  • Hose Cotton Duck Cloth:  Soft, open, plain weave, plied yarn cotton duck cloth.  This cotton duck cloth was originally used as a liner for garden hoses.
  • Biscuit Cotton Duck Cloth:  The heaviest range of numbered ducks.
  • Chafer Cotton Duck Cloth:  Medium texture, balanced strength, weights ranging from 8 to 17 oz/sq. yd.  Low weight single yarn chafer cotton fabric were generally used for bagging, box spring and mattress covers, linings and upholstery end uses.
  • Enameling Cotton Duck Cloth:  Single or double filled flat ducks.  This cotton duck cloth usually has two warp yarns that lay parallel to each other when woven.  Used for rubber industry liners, canvas footwear, coats, aprons, book binding and other uses.
  • Flat Cotton Duck Cloth:  This is a term used for a single and double filled canvas ducks because two strands of single yarns are woven side by side(warp yarn) interlacing with a filling yarn.
  • Shelter Tent Cotton Duck Cloth:  Plain carded cotton duck cloth with with 2 plied yarns in both warp and weft.  The weight of this fabric is roughly 8.5 oz/sq. yd.  This fabric is still used for small portable tents.
  • Sail Cotton Duck Cloth:  Hard construction numbered ducks used in military equipment, tarps, covers, ground cloth, filter cloth, coal bag and other heavy duty applications.
  • Paper Felt Cotton Duck Cloth:  Heavy-weight duck canvas used as conveyor aprons in paper making machinery.
  • Press Cotton Duck Cloth:  Heavy-weight plied yarn cotton duck cloth, loosely woven in balanced construction.  Originally used with cider presses.

What is Polyester duck?

Polyester duck is usually plain weave fabric made from spun polyester yarns.  Polyester is a man made fiber, and it’s available in staple (spun) or Filament yarns.

What is Muslin?

This is a cotton (or sometimes cotton/polyester blended) plain weave fabric, with a high density of threads and generally available in width up to 144″, in weights 3 to 5 oz/square yard, in natural & colors.

What is Linen?

Also known as Flax fabric, produced from the yarn made from the flax plant. Linen is preferred by some artists due to its body and its uneven surface texture. The word “Linen” today generically refers to all bed/bath textiles (not made from Flax fiber).

What is Unprimed/Primed/Greige/Processed Fabric?

  1. Unprimed fabric also known as greige/grey/natural fabric is one that has not been treated after being woven. That is, it is “loom-state”.
  2. Primed fabric is one that has been coated or “primed” on ONE SIDE of the fabric, with layers of acrylic gesso or other primers. It is then ready for stretching/painting.Primed canvas widths will likely be about 1″ lower than unprimed width – this is to say for example, that a 60″ primed canvas will be primed about 59″ wide on a 60″ raw fabric
  3. Processed fabric is fabric that has gone through bleaching/dyeing & other finishing processes.

What is stretched canvas?

Canvas that has been primed & stretched on to a wooden frame. These come in various sizes. This is now ready for the artist. A lot of more experienced painters prefer to prime and/or stretch their own canvas. All our primed artist canvas fabrics are excellent for stretching.

Why should I use CanvasETC Products?

  1. Canvas ETC never compromises quality due to cost pressures. While most available artist canvas today is lighter & coarser, CanvasETC has maintained the old higher standards. We give below examples of the average weight of CanvasETC canvas/duck compared to competition (greige/natural canvas in oz/square yard):
Product CanvasETC Competition
#12 duck cloth 11.80 11.50
#10 duck cloth 15.00 14.40
#08 duck cloth 18.50 17.50
#06 duck cloth 21.00 19.80
#04 duck cloth 24.50 24.00
#01 duck cloth 30.50 29.50
10 oz duck cloth 10.00 9.60


  1. Our Primed canvas is double acrylic coated & adds about 3 oz/square yard to our basic fabric weight. So our 10 oz primed canvas actually weighs around 13 oz/square yard.
  2. Our cotton duck cloth fabrics are manufactured on the latest machines and tested with modern equipment.
  3. Primed canvas is primed about 1″ less than shown. For example a 60″ wide primed canvas will be a 60″ wide fabric with about 59″ of the width primed & about 1″ on the edge which will not be primed.

How should I select a Canvas?

  1. For Painting – The most commonly used canvas are the 7 oz, 10 oz, #12 & #10. The #12 duck is however the only one easily available in a wide range of widths from 36″ to 144″.
  2. For Floor-Cloth – The heavy fabrics like #1,#4,#06, #08, #10
  3. For Photo Backdrops – The wide-width muslins (natural & colors) and the wide width #12 duck.
  4. For Aprons/Bags – the Single Filled ducks for cheaper products (natural/dyed) and any of the numbered ducks for more expensive products.

What is Khadi paper?

Khadi papers are made in India from 100 percent cotton T-shirt cuttings & rags.

What is special about Khadi paper?

Khadi paper is made from cotton rags which have longer fibers than the shorter fluffy fibers of cotton seed commonly used in papermaking. These longer fibers contribute to give exceptional strength & durability. Our sheets are tub-sized (surface sized) with gelatin, which produces a hard water resistant surface. This allows water color to be worked over the surface without penetrating the paper. The paper can be used for all painting & drawing media; for oil paint, it is necessary to prime with gesso or acrylic.

What other benefits are derived by my using Khadi paper?

The water used in the paper making is completely recycled. The virgin water used for white papers and then recycled for colored papers. NO CHLORINE or HARMFUL CHEMICALS ARE USED. The final run off is pH neutral and used to irrigate an organic mango farm. Small scale papermaking also has a positive impact on the local economy in India as it generates employment in poor villages. A majority of these workers are women, leading to their up-liftment from their traditionally passive roles. Khadi paper is NOT made from wood pulp & hence has no adverse impact on the World’s forest resources.
