1. Introduction

These guidelines outline the elements which make up the CLARIN house style. Visual consistency leads to improved recognisability of CLARIN, both on a general as well as national level.  

National nodes and individuals wishing to visually align their output with the CLARIN ERIC style, can find some basic guidelines below.

    If you have any questions regarding the CLARIN house style please contact communications [at] (communications[at]clarin[dot]eu)

    2. Editorial Cornerstones

    To achieve consistency across the network, please follow the following guidelines for written text: 

    • Spelling. CLARIN uses British English spelling. Note that verbs take the -ise ending (i.e. realise), and nouns should end in -our (i.e. behaviour) and -re (i.e. centre).
    • Punctuation. Use hyperlinks for additional information in online texts, not brackets or footnotes.
    • Plain English. We aim for simple, straightforward writing that avoids unnecessary complexity to ensure accessibility for a wide range of users.
      • As a general rule and for reasons of stylistic consistency, the standard usage of English in Britain and Ireland should be preferred (called ‘British English’). The first spelling given on the Oxford Dictionaries website should be followed.
      • For the spelling of CLARIN centres we use: X-centre (not X-Centre, X Centre or X centre)
    For the guidelines for the CLARIN Newsflash, please see this link.


    3. CLARIN Logo

    Please refer to the overview of logos for both the general and CLARIN centre logos to find a version in a suitable format and resolution.

    • The colour of the logo is always dark blue, if possible. Otherwise black or white is used.
    • The logo can be used with or without the subtitle. The subtitle reads “Common Language Resources and Technology Infrastructure”.​
    • The ‘Contribution to CLARIN’ logo can be used to put your contribution to CLARIN, such as web applications (e.g. processing tools & concordancers) and repositories and related pages (e.g. depositing) in the spotlight.​

    4. Typography

    The font to be used within the CLARIN identity is Source Sans (single typeface), both for online (web) and offline (print) use.

    When chances are high that the computer used for editing does not have Source Sans installed, 'Calibri' can be used as a replacement (e.g. in  MS Word and Powerpoint).

    The following table provides information on obtaining or embedding the font:

    Source Sans 3


    <link href=",400i,700,700i&amp;subset=latin-ext,vietnamese" rel="stylesheet">

    font-family: 'Source Sans 3', sans-serif;


    Please note: When you install the Source Sans font, it will only work with the computer you've installed it on. Custom fonts that you've installed on your computer may not display the same way on a different computer. If your document is to be used on such a computer, the font Calibri is to be used. Calibri ships with each version of Microsoft Office, since Office 2007.

    5. Colour Palette

    This palette should be used across all CLARIN communications.

    There are three core colours in CLARIN visual identity. CLARIN uses the three main colours: dark blue (logo colour), turquoise (secondary colour) and spring green (tertiary colour) (plus lighter shades for contrast, if desired):

    The CMYK colour model is used in the printing process. Full-colour printing is preferred, but Pantone colours can be used instead.

    6. Tips for Image Use

    Where possible, the use of real images (i.e., photographs) is preferred. Select or edit images according to the orientation (landscape or portrait) of the space where they will be used.

    When choosing images make sure the text is easy to read (aim for a dark background without complex graphics).

    Try to use only good-quality images (file size can be an indication of this, anything with a very small file size is likely to be poor quality).

    Generally speaking landscape orientation will be easier to work with.

    Try to find more than one image that could work and experiment to see which has the desired outcome.
