US and Canada Sizes (ANSI) for Flyers

These are the standard sizes for flyers used across the States and Canada.

Half Sheet

This is a small flyer size, at 5.5 by 8.5 inches (139.5 x 216 mm), usually used for non-folded promotional flyers. It’s also very cheap to print. 

Standard Flyer

Equivalent to a US Letter page size, at 8.5 by 11 inches (216 x 279.5 mm), this flyer is widely used across the States and Canada and is considered the industry standard. 

This versatile size can be folded in half (to create a half-fold flyer), twice (to create a tri-fold, z-fold or gate-fold flyer) or three times (to create a four-panel accordion fold).

Large Format Flyer (Tabloid)

The tabloid format can, as its name implies, be used for small-format newspapers, but it can also be folded to create a large format flyer. It measures in at 11 by 17 inches (279.5 x 432 mm).

US and Canada Sizes (ANSI) for Posters

These are the standard sizes for posters used in the USA and Canada.

Medium Posters

These two poster sizes, 18 by 24 inches (457 x 609.5 mm) and 19 by 27 inches (482.5 x 686 mm), are commonly used in colleges and schools and are the perfect size for showcasing charts or photographs. 

Large Posters

These large poster sizes, 24 by 36 inches (609.5 x 914.5 mm) and 27 by 39 inches (686 x 990.5 mm), are used for marketing and outdoor advertising. They are also commonly used at trade shows and exhibitions, and in retail as well. 

One Sheet

This is traditionally the standard movie poster size in the US. It's used to promote new film releases—you’ll see the one sheet size, 27 by 40 inches (686 x 1016 mm), at theaters and posted up in retail areas.

International Sizes (ISO 216) for Flyers

These are the standard sizes for flyers used internationally (except Canada and the United States [see above], Mexico, Colombia, and the Dominican Republic).

DL 

DL stands for ‘dimension lengthwise’. This compact flyer size is one-third of a sheet of A4 (99 x 210 mm). The DL term can be confusing, as this means that the flyer is designed to fit inside a DL envelope (which is a bit larger, at 110 by 120 mm).  

This format is tall and slim, and it works well for pamphlets promoting a single offer. 

A5

Slightly wider than a DL size, at 148 by 210 mm, this petite size is also often used for pamphlets and cheap-to-print flyers.

A4

Moving up the A-format scale, A4 (210 by 297 mm) is the European sister of the Letter size in the US. This size can be folded in various ways, and it can also be printed from most home and office printers.

International Sizes (ISO 216) for Posters

A3

The sizes for posters move upwards through the A sizes. Because A3 (297 by 420 mm) can be printed from many home and office printers, you’ll see this size used for school, college, and community posters. 

A2

Twice the size of an A3 sheet at 420 by 594 mm, A2 is used for marketing purposes and to promote music events. 

A1

A large A-size at 594 by 841 mm, this can be used for a wide variety of purposes.

A0

A generous poster size at 841 by 1189 mm, again this is used widely for marketing and advertising purposes.

One Sheet

This standard US movie poster size, which measures up at 27 by 40 inches (686 x 1016 mm), is sometimes used to promote movies in some other countries, such as the UK and Australia.
