The Size of Arrow in the Stroke Panel

Hi winfield_xiao,

if you refer to arrow head scaling using InDesign CC 2017 the range goes from 1% to 1000%.

Unfortunately the percentages do not follow a linear proportionality of the size we see with 100%.

My view: That's a big conceptual failure of the feature.

What you can do to get the size of the arrow head below that limit:

1. Multiply your stroke weight by 10 to 10 pt

2. Lower the percentage of the arrow head scaling until it fits your needs in proportion of the stroke

Beware of a different limit here: Scaling below 65 % could mess with the shape of your arrow head, because the stroke will overlap the arrow head. Another conceptual failure.

3. Go to Preferences > General and set the scaling preferences to Adjust Scaling Percentage

4. Scale the object to 10%

Here two screenshots from my German InDesign.
Note that I scaled the view to a maximum of 4,000 %

Depending of the kind of stroke and the kind of arrow head sooner or later you'll see, that the stroke will overlap the arrow head:

Apparently this is a limitation. But you may control your arrow more efficiently in Illustrator, copy it from there then paste it in InDesign if necessary however it will be compound or grouped object.
