Rolling Smart Ruler by Sharper Image

The Rolling Smart Ruler by Sharper Image makes it easy to measure straight lines, curved lines, bumpy surfaces, and hard-to-reach areas with greater convenience than a standard ruler or tape measure. Simply hold the roller wheel against the surface and roll it forward or backward to capture the measurement.

Perfect for DIY projects, home improvement, crafting, sewing, decorating, measuring window panes, and everyday tasks, this compact digital measuring tool helps take the guesswork out of awkward measurements.

Measures Straight, Curved, and Bumpy Surfaces

Unlike traditional rulers that work best on flat straight lines, the Rolling Smart Ruler can follow curves, corners, uneven surfaces, and contours. It automatically accounts for its own body size when measuring obstructed areas, making it useful for spaces where a tape measure may be difficult to position.

Use it for walls, frames, furniture, fabric, craft materials, cylindrical objects, and more.

Circumference and Diameter Calculation

The Rolling Smart Ruler can measure the circumference of cylindrical objects and automatically calculate the diameter, making it especially helpful for round items and project planning. It measures in inches, feet, or centimeters, giving you flexible unit options for different tasks.

With measuring capability up to 325 ft., it’s a versatile tool for small details and larger projects alike.

Backlit Display, Audio Mode, and Memory

The backlit LCD display makes measurements easy to read, while optional audio mode can read results aloud for added convenience. A memory function stores the last 10 uses, helping you quickly reference recent measurements without writing everything down.

Compact, USB rechargeable, and easy to store, this smart ruler is a useful addition to toolboxes, craft rooms, offices, and home project kits.
