Hi. You can create a text and conform it to a very curvy path by using Text > Put on Path ... a standard process. But typically, unless you play with the kerning of the text, or have an "exact" curvature length, the result is text that may be short of the curvature length, or bunched together.

Here, for Windows 10 (probably earlier Windows versions too) is a process to get an "exact" fit of the text to your desired curve length.

See the attached screen captures below for the steps.

(This process will also work for non-text items, such as objects, symbols, etc.)

Enjoy a great day.

Hi Ken, this is interesting! I make maps in Inkscape and have often used the text on path feature. But, as you mention, it can be awkward with a particularly wiggly line... like a river. I hadn't thought to try Pattern Along Path, but I'm making a mental note for next time.

Thanks for sharing. 😀

Thank you, too.

Hi Ken,

You have developed a must-know technique!  I really love what I see.  Your explanation is great.  It makes all the sense in the world.  Many thanks for extending and expanding it!

With great appreciation,

Roy

P.S. Many thanks for extending and expanding our world, that is!  Roy

Thank you, Roy.

Great Idea, well executed. As Roy statet, this is a "must know" technique
