Overview Quick Measure provides fast, precise distance measurements directly in Blender’s 3D Viewport. Measure between objects, vertices and arbitrary points without leaving the viewport. The add-on is GPL-licensed and designed to speed up modeling, rigging and layout work.

Installation

1. Download the Quick Measure add-on ZIP or folder.
2. In Blender: Edit → Preferences → Add-ons → Install...
3. Select the downloaded file and click Install Add-on.
4. Enable “Quick Measure” in the Add-ons list.
5. Close Preferences. The tool appears in the Viewport (see Location).

Location Viewport → Measure Measurement controls and results are displayed directly in the 3D Viewport overlay.

Quick Start

1. Enable the add-on in Preferences.
2. Open the 3D Viewport and switch to the interaction mode recommended by the add-on (Object/Edit as needed).
3. Activate the Measure tool from Viewport → Measure (or from the toolbar if visible).
4. Click the first point (object surface, vertex or free point).
5. Click the second point. The distance will be shown in the viewport overlay.
6. Repeat or clear measurements using the tool UI.

What You Can Measure

• Distances between object origins or surfaces
• Distances between mesh vertices

Reading Measurements

• Measurements are shown as numeric overlays adjacent to the measured segment.
• Units follow Blender’s scene unit settings (Metric/Imperial).
• Precision and display format may be adjusted in the add-on settings (see Settings).

Settings & Preferences Open Blender Preferences → Add-ons → Quick Measure to configure:

• Display precision (decimal places)
• Unit handling (follow scene units or use a fixed unit)
• Overlay style (font size, color, visibility)
• Snap behavior (vertex, edge, face preference)

Tips

• Use Blender’s vertex/edge snapping to select precise geometry points before measuring.
• Switch between Object and Edit modes to measure object-to-object and vertex-to-vertex distances.
• Lock the viewport view (Numpad / and view locking) to maintain stable camera perspective while measuring.
• For repeated measurements, keep the tool active and clear only older segments you no longer need.

Troubleshooting

• Measurements not visible: check overlay visibility (Viewport Overlays) and add-on display settings.
• Incorrect units: confirm Scene Properties → Units and the add-on’s unit preference.
• Cannot pick vertices: ensure you are in Edit Mode for mesh-level vertex selection, or enable vertex snapping.
• Add-on not listed: confirm Blender version is 2.93 or newer and that installation succeeded.
