The default scale of a profile in Surfer for the X axis is 6” and the Y axis is 1.5”. This is unrelated to the units on the X and Y axes.

You can change the scale in the profile properties:

1. Select Profile in the Contents window.
2. Click the Scale tab in the Properties window.
3. Change the scale of one direction; or for proportional scaling, check the Proportional XY scaling check box and change the scale.
