Step 5 – In the ‘preferences’ menu, under ‘general’, locate ‘scale stroke and effects’.

Step 6 – Uncheck this option.

Step 7 – Click ‘ok’ to return to the canvas.

Step 8 – Repeat steps 1-3. With your stroke window open, select an object on your artboard with stroke applied with the selection tool, and check the weight.

Step 9 – Click and drag one of the corners of the transform box, and scale the image larger or smaller. Once released, your stroke should stay the same weight. You can turn stroke scaling back on at any time by returning to the preferences panel.


Stroke scaling is one of those options that is so simple to toggle on or off, but can initially be very frustrating to deal with when you don’t know where that option is.

The ‘preferences’ menu is home to a lot of features like this, so if you do get stuck with other issues it’s always a good menu to start with to see if you can make any quick changes. I hope this simple tutorial helps you get out of a jam!
