Hehe, we're back to the question "what is one pixel" and as far as Inkscape (since 0.92) is concerned 1 px is 1/96 inch, so it is a real world size and this pixel size in fact *is* the standard pixel size according to CSS2. Y'all should really read Mc's posts on units. ;-).I prefer A4 as a default with mm as the measurement (as it is). The reason is that I design stuff in Inkscape every day. I use its measurements in mm, and the default gives the user a real world size to compare too. There is no standard pixel size, so it does not make sense to me to have the default in pixels, or indeed to measure anything in pixels at all. Pixel widths are only good for exporting bitmaps, and you will be at the mercy of whatever the manufacturer of the device decided the pixel density should be.
I don't disagree that a mm is a useful unit for many applications (I think you misunderstood me here). I'm fine with keeping the default template being A4 (with mm measurements) and set all lengths in mm by default. What I would change is the unit length we use in the SVG - here I think we should stick with px by default (remember it can always be changed by the user if they have special needs!) as it has the least unwanted side-effects and works very well for many use cases and well for most others. I think that can't be said for the current solution (which I feel works well for some cases and badly for many others).Keep in mind the criticisms we got from the artists and illustrators for the last release. It's clear to me from those that the uses for Inkscape go far beyond just SVG for web. There was a whole classroom full of students who randomly happen to be using Inkscape in the next room for CNC machines. Ask them what they would prefer, and they will probably say mm makes the most sense.
Well, then we rescale again... Now that we put in viewBoxes by default it's not a big deal. In the worst case we end up with what we now produce by default (scaled SVG).If we choose px as the base unit for measurement the dpi (and thus conversion to mm and other physical measurements) will change again to some other completely arbitrary increment in the future. Whereas 1mm will always be 1mm.

For what it's worth I also prefer a px-based default template.
- For digital art it makes the most sense as Tyler noted.
- For stuff that's intended to be used "on paper" it does not break anything and can in fact even avoid incompatibilities due to the viewbox scaling. Also it feels more natural to make a line 1or 2 px wide (which are useful widths for me in everyday use) instead of fiddling with fractional millimeters. If I need mm-based sizes I can also still use them where necessary.
On a related note I'm not even sure our default size of A4 is overly useful. I've yet to create content in Inkscape that would need an A4 size... For me it's either digital artwork which has some even pixel size or I'm creating graphics that are put on A4 paper and therefore need to be smaller anyway (e.g. ~ 8cm wide to fill one column). So, while we need some default (which might just as well be A4) I don't think we should assume users actually create A4 content and base our decision on that.

I see no downside to having all releases/localizations use px as display units and scale=1.
AFAICT, it breaks nothing, which cannot be said for other current defaults. Everything works and no gymnastics trying to explain units and scale to the non-technically inclined.
Even the newest users can understand how to set the document to their preferred display units. No need for typical users to change scale.
Simple rationale: svg is a web format, hence default.svg units = px.

Oh, I didn't know about these templates!
However, I think it's better for users to know how to use the interface, rather than use a template which only sets up the units, and not the page size (unless you happen to want an A4 page).
I'm not clear what you mean by this:
The one thing you cannot do, however, is modify the document units afterInkscape has opened the startup file.
If you know how to change the units (as I've just learned how to do it correctly) can't they be changed? Or do you mean that the user would have to save a new template if they change the units?
I'm just writing the new FAQ item right now, so I'll include this info about the templates too. But need to understand that last statement (above).
Thanks Alvin :-)

Subject: Re: [Inkscape-user] the Scale setting and Display units
It may be worth mentioning that you can choose the document units that you
prefer when you start up Inkscape. If you use the startup template file
C:\Program Files (x86)\Inkscape\share\templates\default.svg (which is the
default), then you will find that the document units are mm. You can confirm
this by drawing a rectangle that has the width of the full page and then
using the XML editor to confirm that the width has been expressed in mm. A
typical example would be
<rect
style="..."
id="rect10"
width="210.91072" (should be 210, my hand was shaky)
height="88.446426"
x="0"
y="0.66666663" />
If you prefer to use px as the document units, then use the template file
C:\Program Files (x86)\Inkscape\share\templates\default_px.svg. In this case
if you draw a rectangle that has the full width of an A4 page you will get:
<rect
style="..."
id="rect18"
width="797.14288" (should be 793.7007, which is 210mm expressed in
px)
height="357.14285"
x="0"
y="2.519685" />
If you prefer to use pt as document units, then use the template file
default_pt.svg
If you want to permanently modify the startup units, then copy a file like
default_pt.svg to overwrite the file default.svg. (after first making a
backup, just in case.)
The one thing you cannot do, however, is modify the document units after
Inkscape has opened the startup file.
hth,
Alvin
