Scale

Mode: Object and Edit modes

Hotkey: S

Menu: Object/Mesh/Curve/Surface » Transform » Scale

Description

Pressing S will enter the Scale transformation mode where the selected element is scaled inward or outward according to the mouse pointer’s location. The element's scale will increase as the mouse pointer is moved away from the Pivot Point and decrease as the pointer is moved towards it. If the mouse pointer crosses from the original side of the Pivot Point to the opposite side, the scale will continue in the negative direction and flip the element.

Basic scale usage. From left to right, the panels show: the original Object, a scaled down Object, a scaled up Object and a scale-flipped Object.

There are multiple ways to scale an element which include:

  1. The keyboard shortcut (S)
  2. The 3D manipulator widget
  3. The Properties menu (N)

Basic scale usage and common options are described below. For additional information, you may wish to read the Transform Control and Orientation pages which provide more information about options such as Precision, Axis Locking, Numeric Input, Snapping and the different types of Pivot Point.

Usage

Scaling using the keyboard shortcut

  1. Use RMB Template-RMB.png to select the elements you want to scale.
  2. Tap S once to enter scale mode.
  3. Scale the elements by moving the mouse.
  4. LMB Template-LMB.png click to accept changes.
The amount of scaling will be displayed in the bottom left hand corner of the 3D window.
Scale values

Constraining the scaling axis (axis locking)

Scaling can be constrained to a particular axis or axes through the use of Axis Locking. To constrain scaling, the following shortcuts can be used:

  • S, X: Scale only along the X Axis
  • S, Y: Scale only along the Y Axis
  • S, Z: Scale only along the Z Axis

Axis locking can also be enabled by pressing the MMB Template-MMB.png after enabling scaling and moving the mouse in the desired direction e.g.

  • S, move the mouse along the X axis, MMB Template-MMB.png: Scale only along the X Axis

Fine Tuning The Scaling

Precise control can be had over scaling through the use of the ⇧ Shift and Ctrl keys to limit scaling to discrete amounts. You can also enter a numerical value in Blender Units (BU) to specify the amount of scaling after after initiating a scale transformation.

  • Hold Ctrl down while scaling to scale the selected element in degree 0.1 BU increments.
  • Hold ⇧ Shift down while scaling to scale the selected element in very fine increments.
  • Hold ⇧ ShiftCtrl down while scaling to scale the selected element in 0.01 BU increments.
  • Press S, type in a number and press ↵ Enter to confirm.

Orientation dependent scaling
By default, all scaling happens around a Global Orientation. You can change the scaling orientation by pressing the axis key twice. For example, pressing S, X, X will by default set scaling to occur around the local orientation.

Scaling with the 3D Transform Manipulator

Scaling Transform Manipulator

In the 3D View header, ensure that the Transform Manipulator is enabled (the red, green, and blue triad is selected). Set the manipulator type to scale (the highlighted square icon shown below).

  1. Select your element with RMB Template-RMB.png.
  2. Use LMB Template-LMB.png and drag any of the three colored axes on the scaling manipulator to scale your object along that axis. You can also use ⇧ Shift, Ctrl or numeric input with the 3D manipulator widget for further control.
  3. Your changes will be applied when you release LMB Template-LMB.png or press Space or ↵ Enter. Your changes will be cancelled if you press RMB Template-RMB.png or Esc.

Scaling with the Properties Panel

Scale transform properties panel.

Scale values can also be specified in the Properties panel (N) by altering the amount value in the scaling slider of the Transform panel. Scaling along particular axes can be enabled or disabled by toggling the padlock icon.
