Alexandre -

There are instructions for a couple of ways of doing what you want at https://superuser.com/questions/128814/how-to-create-an-inner-border-stroke-in-inkscape. The easiest way may be to use the trick near the bottom of the page, of unsetting the option (an icon on the toolbar at the top) that says 'When scaling objects, scale the stroke width by the same proportion'.

(I sent this message yesterday but it was blocked because the 2 images made it too big. I have now removed them.)

Hi Robert!

I'm also not familiar with path tools.
I expected there to be a "lock", to fix the external size of the object, regardless of the thickness of the border.
But it seems that there is no such option in inkscape.

It is very annoying to have to correct the size after changing the thickness of the border.

Thanks by answer.

Below, follow a example...

I think that what you are looking for is a stroke that is inside the object boundary rather than centred on the object boundary. I believe that the former is not available in Inkscape and is not supported by the SVG standard. However, I think you can get the effect you want using Path > Inset, or Path > Dynamic Offset, or Path > Linked Offset, or Path > Path Effects + Offset. They provide different levels of control.

I'm not very familiar with these tools and don't know where the best documentation is. In playing with them I used various combinations of Edit > Copy & Paste In Place, Object > Raise & Lower, Path > Object to Path, and Object > Fill and Stroke.

Hi Folks!

How to maintain the external size of an object by changing its border thickness?
Every time I change the border thickness, the object size automatically changes as well.
This is really annoying, because I have to resize again...but in that case the border thickness changes too.
So I'm going to repeat this boring procedure until I get it.

Thanks in advance
