Hi all,

in one of my mails this evening I proposed to show you my thoughts about the minimal size we want our logo to be used.

In my eyes the most crucial part in this decision is about the readability and general impression of the textual parts.

As we allow to use our logo in parts (text only or symbol only), we should define minimal sizes for both:

While the symbol (used as website favicon and small mimetype icon) has already proved that 13x16 px is a size where it is still readable, it's different for the text "LibreOffice".

I tried to reduce the size including the necessary white space (BTW: I defined the whitespace in the text-only logo as the height of the "i" without dot), but it depends very strong on sub-pixel movements of the logo.

If the vertical lines (in L,i,b,f,f,i) are positioned in a way, that most of them fill one or more than one pixel, the look sharp. If they don't align, they are greyish.

On the other hand the dots of the "i" characters look very imbalanced by such an approach.

I tried both positionings in three sizes (equivalent to 12px, 15px and 18px), so I'd like to ask you, where we should define the minimal logo size (and update the wiki page accordingly).

Here is the image containing both versions:

While I think the 12pt version is too small (in the dot aligned version the lower border of the logo is not clear), the 15px version might work, if people use exactly the "dots aligned" position for this graphic.

So I'd like to propose:

If you work on your own artwork containing our logo, it should not be smaller than 98x30 px (nearly about 18pt).

For use-cases where extra small logos are requested, we recommend to use the pixel adjusted version of an 82x25px logo (about 15 pt).

Does this sound reasonable?

Thoughts, opinions, corrections?

Best regards
