19″ Rack Panels and their dimensions

When clients contact us about our various flight case racks and portable server SKB Rack Cases etc. we are often asked how many ‘Rack Units’ do I need for my 19 inch equipment.

Not everyone has been around rack units, ECA, ECIA, DIN 41494 and IEC 60297-3-100 standards and can be understandably confused.

So for those who have yet to become an anorak on the 19″ system this is for you, a laymans guide to the 19″ rack panel dimensions.

The standard rack unit, also known in short as a U, RU or HE, was originally specified as an imperial dimension at 1.75 inches. Now days of course many countries have moved over to the metric system where 1U converts to 44.45mm, different numbers but the same physical height.

Rack Units are just multiples of these dimensions, 4U = 4x 1.75″ = 7″ or 4x 44.45mm = 177.80mm

The following table will allow you to calculate the number of Rack Units you require for any given height of rack mounting equipment or visa-versa.
