SketchUp Instant Dimensions – Live Width, Depth, and Height While You Model

Sketchup Instant Dimensions extension

When working in SketchUp, one of the most common interruptions in the modeling flow is a simple question: “What are the dimensions of this object?”

Whether you are designing architectural spaces, furniture, interiors, or technical layouts, checking width, depth, and height happens constantly. Yet SketchUp still requires users to interrupt their workflow by using the Tape Measure tool, adding temporary dimensions, or opening extra panels.

That friction is exactly why I created SketchUp Instant Dimensions.

The Problem: Checking Dimensions Breaks Flow

In real-world SketchUp workflows, users often need quick size feedback:

  • Architects verifying room proportions
  • Designers checking furniture clearances
  • Woodworkers validating part sizes
  • Makers ensuring components fit within constraints

Yet SketchUp does not provide a simple, always-visible way to see the dimensions of a selected object. Instead, users must:

  • Activate the Tape Measure tool
  • Manually click edges or points
  • Add temporary dimensions that clutter the model
  • Repeat this process dozens of times per session

Over time, these small interruptions add up and slow down modeling significantly.

The Solution: Instant Dimensions in the Status Bar

SketchUp Instant Dimensions solves this problem by displaying live measurements directly in SketchUp’s status bar.

When you select an entity; group, component, or multiple objects, the extension instantly shows:

  • Width (X)
  • Depth (Y)
  • Height (Z)

The measurements update automatically as your selection changes and disappear when nothing is selected. There are no dialogs, no overlays, and no extra tools to activate.

It feels like a native SketchUp feature—because it behaves like one.

Why Live Dimensions Matter for Architecture & Productivity

In architectural and design workflows, speed and clarity are critical. Live dimensions help by:

  • Allowing instant size verification without stopping modeling
  • Reducing visual clutter from temporary dimensions
  • Keeping focus on design decisions instead of measurement tools
  • Improving accuracy when working at scale

Because the extension uses the selection’s bounding box, it works reliably with groups, components, and multi-selection—making it ideal for layout checks, space planning, and proportion control.

Designed to Be Simple (On Purpose)

SketchUp Instant Dimensions is intentionally minimal:

  • No menus
  • No settings
  • No configuration
  • No visual overlays

You select an object, read the measurements, and keep modeling.

This design keeps the interface clean and avoids the complexity and maintenance overhead found in heavier measurement or reporting extensions.

Final Thoughts

Small workflow improvements make a big difference over time.

By providing instant, always-available dimension feedback, SketchUp Instant Dimensions removes one of the most common interruptions in everyday modeling.

If you frequently check object sizes while designing, this extension will quietly save you time—every single session.
