When proportional editing is enabled in edit mode, then if you select and drag a point, nearby points will also move with it. The effect has a certain radius. How can you set this radius?

According to the documentation I found, you can set it using the scroll wheel or PgUp/PgDn. I tried those, but PgUp/PgDn seem to do nothing, and the scroll wheel instead zooms. What's the correct way to do it?


You must press PgUpPgDown or use the scroll wheel during a transform action such as Translate (G), Rotate (R), or Scale (S).

During a transform operation, you can see the proportional size visualized as as a circle around the Pivot point and you can see the actual proportional size value displayed in the Header:

In the Redo panel located at the bottom of the Tool Shelf (N in the 3D view) or found by pressing F6, there is a slider to adjust the Proportional size. Note that this only applies immediately after a transform operation.

    $\begingroup$ also you only see the ring when you are in the transform mode. $\endgroup$ – Vader Feb 19 '14 at 2:26
  • $\begingroup$ For anyone working out and about on a Mac laptop (so trackpad - no mouse), you can adjust the sphere of influence using fn + Page Up / Page Down. $\endgroup$ – GLCoder Aug 25 '16 at 20:23
  • $\begingroup$ and further to GLCoder's perfectly correct advice, if you're using a Mac wireless keyboard + wacom tablet, you can assign buttons on the tablet to fn+Page Up/Page Down (a key combination almost impossible for me to achieve on the wireless keyboard, so far apart as they are) $\endgroup$ – user3849061 Apr 11 '18 at 10:18
  • $\begingroup$ For macbook pro trackpad with mouse gestures on, just slide two fingers up or down like you would do for scrolling... saves having to use multiple key strokes. $\endgroup$ – neoscribe Jul 9 '18 at 6:33

Select one ore multiple vertex points and scroll with your mouse wheel.

  • $\begingroup$ @DuarteFarrajotaRamos explain how this does not answer the question. You can use the mousewheel to change the radius, it works perfectly fine for me. $\endgroup$ – Black Jun 1 '17 at 8:02

    $\begingroup$ It does a poor job at explaining when to use the mouse wheel (during transforms), which was the initial difficulty of the poster. It also adds nothing new to gandalf's answer which already covers it well.This question is also quite old, from 2014, try answering a newer one ;) $\endgroup$ – Duarte Farrajota Ramos Jun 1 '17 at 13:21

For fine tuning you should use Shift+Page Up/Page Down.

For perfect sphere (I was seeking!) Global size (key it in manually) should match Proportional size.
