Editing Movable type (section)

=== National traditions ===
The type-height varied in different countries. The Monotype Corporation Limited in London UK produced moulds in various heights:
* {{convert|0.918|in|mm}}: United Kingdom, Canada, U.S.
* {{convert|0.928|in|mm}}: France, Germany, Switzerland and most other European countries
* {{convert|0.933|in|mm}}: Belgium height
* {{convert|0.9785|in|mm}}: Dutch height

A Dutch printer's manual mentions a tiny difference between French and German Height:<ref>Blankenstein A.H.G., Wetser Ad: ''Zetten, uitgebreide leerstof, deel 1'', p.&nbsp;26, Edecea, Hoorn, The Netherlands, 5th edition, ({{circa}}1952)</ref>
* 62.027 points Didot = {{convert|23.30|mm|abbr=on}} = English height
* 62.666 points Didot = {{convert|23.55|mm|abbr=on}} = French height
* 62.685 points Didot = {{convert|23.56|mm|abbr=on}} = German height
* 66.047 points Didot = {{convert|24.85|mm|abbr=on}} = Dutch Height

Tiny differences in type-height can cause quite bold images of characters.

At the end of the 19th century there were only two typefoundries left in the Netherlands: [[Joh. Enschedé|Johan Enschedé & Zonen]], at [[Haarlem]], and [[Amsterdam Type foundry|Lettergieterij Amsterdam, voorheen Tetterode]]. They both had their own type-height: Enschedé: 65 23/24 points Didot, and Amsterdam: 66 1/24 points Didot—enough difference to prevent a combined use of fonts from the two typefoundries: Enschede would be too light, or otherwise the Amsterdam-font would print rather bold. This was a way of keeping clients.<ref>P.J.W. Oly, de grondslag van het bedrijf der lettergieterij Amsterdam, formerly N.Tetterode, edition: Stichting Lettergieten 1983, Westzaan, pp. 82–88</ref>

In 1905 the Dutch governmental {{lang|nl|Algemeene Landsdrukkerij}}, later: "State-printery" ({{lang|nl|Staatsdrukkerij}}) decided during a reorganisation to use a standard type-height of 63 points Didot. {{lang|nl|Staatsdrukkerij-hoogte}}, actually Belgium-height, but this fact was not widely known{{by whom|date=August 2020}}.
