Imperial Metric Conversion Chart

What Size Postal Tube Is Best For...?

The below is designed to help your decide which postal tube or mailing tube is best for your particular poster, print or artwork in both imperial or metric measurements.


Our cheapest Postal Tubes / Mailing Tubes prices come as standard but you can select numerous other variables when deciding on the right spiral wound cardboard paper postal tube for your items & to minimise postage costs or the price you pay couriers to send them. As manufacturers that hold an enormous range as stock items, we can also manufacture almost any tube you may require. If you have landed on this page because you are struggling to identify the postal tube most suitable for your goods or are unsure of the size Poster Tubes required for your posters check the metric to imperial mailing tubes chart below. 

A quick guide to tubes for standard paper sizes is as follows: A5 postal tubes - 8" or 203mm long, A4 postal tubes - 9.4" or 240mm long, A3 postal tubes - 13" or 330mm long although some people use 14" (355mm), A2 - 17.5" or 448mm long , A1 postal tubes - 25" or 635mm long or B size tubes. Individual postal tubes can also be supplied in numerous lengths. Visit the diameter page to buy single tubes.

Using the Table below to Identify the tube you need: the column in red is the usable length of our storage or postal tubes with the reduction made for the use of OUR plastic end caps (end caps from other manufacturers may differ). So use this column to identify the usable length of the postal tube required for your document, map, poster etc. The overall length of the cardboard tube with the usable length you need is shown in mm, cm, or inches in the other three columns.

When attempting to work out the best diameter to use, it is a good idea to roll the item to be inserted and put an elastic band around the item so you can measure the diameter of the poster etc.

Please note: when you buy our postal tubes, we quote the diameter (the measurement across the opening of the tube) we do not quote in radius or circumference. Please visit our main postal tube selling page to select the diameter you require here
