To obtain paper sizes in centimetres, convert mm values to cm by dividing by 10 and in feet by dividing inch values by 12.





4A0 & 2A0 – The DIN 476 Oversize Formats

The origin of these formats is in the German DIN 476 standard, that was the original base document from which ISO 216 was derived.


A Series Paper Size Tolerances

ISO 216 specifies tolerances for the production of A series paper sizes as follows:

±1.5 mm (0.06 in) for dimensions up to 150 mm (5.9 in)

±2 mm (0.08 in) for lengths in the range 150 to 600 mm (5.9 to 23.6 in) 2


Average lead times for bespoke products

Specialist tapes – 3 days
Cardboard tubes – 1 week
Corrugated – 1 week
Bubble etc – 2 weeks
Corporate clothing – 2 weeks
Printed goods – 2 weeks
Polythene – 2 – 3 weeks

Did you know?

You can buy high strength blends of polythene now that will reduce cost, environmental impact and product damage?
With thinner flutings available now for corrugated products, you can reduce the storage space needed and also save money on the cardboard too.

Board Grades

When deciding which board grade you require there are a number of factors to consider such as, weight of product, storage conditions, printing and presentation.



‘Fluting’ is the corrugation between the internal and external lining papers of the board. The various flutes available offer different properties over each other such as Compression, Crush or Burst strength, Printability or storage space.

  • E Flute
    Board thickness approximately 1.2mm.
    A fine flute which gives an excellent crush resistance and printability
  • B Flute
    Board thickness approximately 3mm.
    The most widely used flute profile due to its all round compression strength, compactness, printability and cost effectiveness.
  • C Flute
    Board thickness approximately 4mm. A larger flute than ‘B’ offering greater compression strength, but can be more easily crushed.
  • BC Flute (double wall)
    Board thickness approximately 7mm A combination of ‘B’ and ‘C’ flute is normally used when compression and stacking strength is important.
  • EB Flute (double wall)
    Board thickness approximately 4.2mm. A combination of ‘E’ and ‘B’ flute offering good strength and printability taking up less storage space than ‘BC’.


Suggested Board Grades for Content Weight

The quality and strength of the board lining papers are generally determined by the weight per square metre in Grams e.g. 125, and also content mix of new and recycled wood fibre Kraft paper (‘K’) being of better quality (higher content of new wood fibre) than Test paper (‘T’).

For example: 125 K/T B would mean the weight of the paper used is 125 grams per square metre, the external paper being Kraft and the internal being Test quality with ‘B’ fluting between.
