Imperial Metric Conversion Chart

POSTAL TUBES / Mailing Tubes Manufacturers Low Prices - If you are unsure of the size Poster Tubes required for your items check the metric to imperial mailing tubes chart below. We can manufacture cardboard tubes in whatever sizes are needed, but you may want to check out the numerous sizes held in stock and ready to ship here.

See Also Paper & Envelopes Sizes Guide if you are unsure as to whether you need A5 postal tubes, A4 postal tubes, A3 postal tubes, A2 postal tubes, A1 postal tubes 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 below is the usable length of our tubes with the deduction 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 you need can be seen in mm, cm, or inches in the other three columns.

You can also view tubes by diameter (radius, circumference)
