Traditional Paper Sizes

In Europe everyone from a school child to your granny knows that you buy A4 paper for your printer at home. It measures 297 x 210 mm every time you buy it because it's a standardised size whether or not you buy it in the UK, Germany or Portugal.

Some people know that A5 is half the size of A4 and often used by card makers and A3 (twice the size of A4) is a popular photographic printing size. 

Professional printers use B size paper. These are slightly larger than A sizes which allows for the paper to be trimmed down to an A size after it's been printed. 

However ordering paper in the old days wasn't quite so simple...

England had its own sizes as did France, Germany and Holland. Instead of an A or B designation they had names. Even more confusingly these names might not even guarantee that you'd get exactly the same size.

Variations in sheet size were common in hand production. Also, some mills measured their paper from the outside edge of each deckle and some from the inside which could account for up to 1/2 inch difference. Grades for printing were traditionally made larger than for writing, hence a further variation of 1/4 - 1/2 inch. 

Here at VPCo our business is buying and selling vintage and antique paper and one of the joys of this is identifying the various sizes which can often inform us what purpose the paper might have been made for. For example, a paper in Post size was almost certainly made for correspondence. It can be identified by its size and often via its watermark; an image of a post horn which may have signified an urgency in delivery. 

Many artists around the world will be used to ordering Imperial sized paper - it's 56 x 76 cm or 22 x 30 inches. In the US it's often called Full Sheet rather than Imperial. Some artists will be familiar with Elephant or Double Elephant and of course Foolscap is a well known size. Perhaps its not so well know that for many years Foolscap paper contained a watermark of hatted Jester or a Fool's Cap. 


A system in which standard sizes were formulated was accepted in Britain in 1836.

Called The Imperial System, its object was to assist the production of a uniform result, thus making it possible to save time, energy and expenditure in manufacture, and allowing the papermaking trade to make a better-informed judgement on quality.

A few years earlier, a similar standardization of traditional British units had taken place in the United States, resulting today in what is known as the U.S customary system.

In the world of fine paper today, the term 'Imperial' is still applied to traditional sizes and linked weights of the premetrication era.


Antiquarian - 51 x 55 in, 787 x 1346 mm

One of the largest drawing papers made by hand in Europe, its size has varied over time between 36 x 54 and 29 x 52 in. It was first made in England, in Kent, by James Whatman in 1773: the moulds for these huge sheets were hoisted on a lifting device called "The Contrivance", with six to eight men required in the dipping and couching processes.

Antiquarian was a popular size for creating architectural and ship building plans.

Atlas - 26 x 34 in, 660 x 864 mm

Extra Large Atlas - 27 x 35 in, 686 x 889 mm

A large size of drawing paper, originally developed for the printing of maps and atlases from engraved plates

Cartridge - 21 x 26 in, 534 x 661 mm

Traditionally a size for wrapping and drawing papers. Originally derived from the Italian cartoccio, paper (carta) for wrapping up a charge of powder.

Colombier - 24 x 34 1/4 in, 597 x 876 mm

This size was standard in England, although foreign equivalents vary. It was popular with American papermakers in Pennsylvania. The original watermark of a dovecote, after which it was named, was a play on the name of the Auvergnat papermaker Colombier.

Crown - 15 x 20 in, 381 x 508 mm

Double Crown - 20 x 30 in, 508 x 762 mm

Quad Crown - 30 x 40 in, 762 x 1016 mm

A printmaking size which has varied historically. The name, from the French demi, indicates that it was originally derived by folding a large sheet in half (possibly a Colombier drawing paper, or an Imperial writing paper). Demy traditionally carried the fleur-de-lys within a shield watermark.

Eagle - 28 1/4 x 42 in, 730 x 1067 mm

An old standard size of drawing paper known as early as 1300, which took its name from a watermark of an eagle.

Elephant - 20 x 27 in, 508 x 686 mm

Double Elephant - 27 x 40 in, 686 x 1016 mm

A sheet also name after its watermark. Double Elephant is also called Grand Eagle. The variations are still particularly wide in the largest sheet of this size.

Emperor - 48 x 72 in, 1219 x 1829 mm

This name has been used for a size of notepaper but more commonly refers to a writing or drawing size. In the US it often means 40 x 60 in (1016 x 1520 mm)

Foolscap - 13 1/2 x 17 in, 343 x 432 mm

Double Foolscap - 17 x 27 in, 432 x 686 mm

Quad Foolscap - 27 x 34 in, 686 x 864 mm

A size for writing drawing and printing which could vary by 2 or 3 inches from the standard given above. The name comes from the watermark of a jester's head (with the cap and bells), introduced to Britain in the mid-16th century; this was replaced in the 18th century by the Britannia watermark. 

Hand - 16 x 22 in, 406 x 559 mm

Royal Hand - 20 x 25 in, 508 x 635 mm

The name derives from the watermark, traditionally a hand or glove, dating back to the 16th century.

Imperial - 22 x 30 in, 559 x 762 mm

Large Imperial - 22 x 32 in, 559 x 813 mm

Half Imperial - 15 x 22 in, 381 x 559 mm

Double Imperial - 30 x 44 in, 762 x 1118 mm

A popular size traditionally for writing and printing papers, in common use today. 

Medium - 18 x 23 in, 457 x 584 mm

Double Medium - 23 x 36 in, 584 x 914 mm

Quad Medium - 36 x 46 in, 914 x 1168 mm

This size occasionally today watermarked with the traditional fleur-de-lys

Post - 15 x 19 in, 387 x 489 mm

Large Post - 16 1/2 x 21 in, 419 x 533 mm

Double Post - 21 x 33 in, 533 x 838 mm

The name derives from the watermark of a post horn, first used in the 14th century

Pott - 12 x 15 1/2 in, 317 x 394 mm

This is the smallest handmade size, used for writing and drawing papers. The earliest Pott watermark illustrates a pot or chalice divided into compartments for holding food and drink. Foreign equivalents vary.

Royal - 20 x 25 in, 508 x 635 mm

Super Royal - 20 x 28 in, 508 x 711 mm

Double Royal - 25 x 40 in, 635 x 1016 mm

Quad Royal - 40 x 50 in, 1016 x 1270 mm

A size for drawing, writing and wrapping, formerly watemarked with an ornamental shield surmounted by a fleur-de-lys.



In Europe, thanks to the metric system we measure the weight of a sheet of paper in gsm or grams per square meter.

This means that we know, no matter how large a sheet of paper is, if it weighs 90gsm or so it's a suitable weight for printing documents on an inkjet printer. A 130gsm paper might be considered a luxury weight for printing or writing letters and 300gsm a great weight for printmaking or watercolour. 

In the Imperial system, before metrication and still used in the US, the basis of weight of paper is expressed in terms of the weight of a ream (now 500 sheets although in the past it might be 472, 480 or 516 sheets) of a particular size.

Thus if 500 sheets of the size called Imperial ( 22 x 30 in) when dry weigh approximately 140lb, the paper is termed 'Imperial 140lb'. This principle can give rise to confusion because sheets appear to weigh more in different sizes e.g. Double Elephant 246lb has the same basis weight as Royal 106lb. 

To convert Imperial weights for various sizes of sheet to gsm, multiply the weight in pounds (lb) per ream by the following factors:

Double Crown 2.34, Demy 3.27, Imperial 2.08, Medium 3.4, Large Post 4.06, Royal 2.81

To convert gsm into the nearest equivalent in pounds per ream, divide the weight in gsm by the same factors - thus 150gsm is equivalent to Imperial 72lb.

    I have been replacing the mat behind an old chalk and charcoal sketch done on either very heavy paper or card stock. It measures 400 mm by 527 mm. I looked on your site to see if I could match those dimensions to a standard paper size but could not quite find a match, although French Ecu – 15 3/4 × 19 5/8 in, 400 × 500 mm matches in one dimension and the other is pretty close, but just a little short. The image shows a man and a woman standing outside near a cottage lifted from the ground on short posts. The man is opening an umbrella and is looking up. It is very nice work and my guess is that the clothing appears to be of a French style of the latter 1700s. There is no inscription, signature or provenance, other than my mother purchased it at an antique store about 60 years ago. Does that paper size match any historic size for such materials that you may know of?

  • Peter Brightbill

    Could you list the most common sizes for different uses (business stationary, personal stationary, invoices, short letters, business cards, visiting cards)?

  • Andrea Watson

    Thank you for all the above information!!! I never realised how much there is to know about paper. I loved reading it all and although I probably only retained a small amount of the info, I now know a lot more about it than I ever did before! I think I’ll come back to read it a few more times. Thank you!

  • Derek Mayes

    Came into the shop; read y’r blog; admire the spirit; love the goods; WISH I had the need to quality paper!
