This digital ruler can handle accurate measurements over almost any surface, including curves

TLDR: The Rollova 2.0 Digital Ruler slips into your pocket and springs to life to measure over any surface, even curves, with just a simple roll.

While the wooden ruler is best remembered as the stereotypical corporal punishment weapon of choice for catholic school nuns, its place in 2021 society is quickly fading into the rearview mirror of history. Who still uses a foot-long piece of wood to measure off inches, centimeters, and other short increments of distance these days?

In the coming years, we’ll probably be able to instantly assess those types of measurements right through enhancements like the ocular implants in our eyeballs. Until that day comes, we’ll just have to settle for steps beyond the wooden ruler — like the Kickstarter darling, the Rollova 2.0 Digital Ruler ($76.95, 13 percent off, from TNW Deals).

Like everything else in our modern world, measurement has gone digital — and this compact, highly-portable electronic ruler makes it incredibly simple to measure short distances easily. That includes gauging over surfaces that would seem mostly impossible with a stiff conventional ruler, like over curved or fixed objects that don’t lend themselves to easy measurement.

At just about 2 inches across, the Rollova 2.0 is about the size of a poker chip. But this pocket-friendly gadget is a designer or craftsmen’s best pal, letting users just roll the ruler over the object or surface and get precise readings on length, width, height, and all those important details.

Crafted with a full stainless steel body, this minimalist tool includes a 1.2-inch OLED screen that displays your findings in either imperial or metric units. The rubber wheel and rugged frame roll effortlessly over your targeted surface, measuring all the way up to 83 feet over almost any terrain, including fabric, metal, wood, and more. It’ll even save your last 99 measurements in its internal storage.

Just pop in a traditional coin-type lithium battery and the Rollova 2.0 can sit in standby mode for up to 2 years, ensuring it’s always ready to jump into action when needed.

RIght now, buyers can save almost $15 off the price of this next-gen measuring tool by picking up the Rollova 2.0 Digital Ruler now at 13 percent off its regular price at just $76.95. Or get a two-pack of Rollovas for even more savings, only $136.99.
