All great things are circular. The sun and moon, the metaphorical circle of life, pizzas, donuts, CDs, the iPod jog wheel, and the Mini Titanium Curve Measure Slide Rule from the folks at Titaner. Sure, that intro sounded rather grandiose, but this humble little torus-shaped device transcends the simple rolling scale. Crafted from a combination of titanium and copper, the Mini Titanium Curve Measure Slide Rule can measure linear and non-linear distances (in multiple units), but it can also add (or subtract) and even multiply using basic logarithmic principles. In short, this tiny handheld device is stationery from an alternate reality, capable of doing multiple things in a form factor mainstream tools haven’t explored before. The added bonus? It doubles as a fidget toy, making it just the perfect EDC for creative-folk.

At first glance, this slide rule stands out with its sleek, circular form. Unlike traditional straight rulers, the TITANER’s hubless ring-shaped design allows for continuous measurements along any surface, whether flat or curved. Its circular construction eliminates the limitations of a fixed, linear ruler, offering limitless potential for measuring longer lengths by simply rolling it along a surface. This continuous loop system is what sets the TITANER apart, making it a versatile tool for designers, engineers, and DIY enthusiasts who often need to measure odd shapes and sizes without being limited by scales and measuring tapes.
Measure irregular shapes so fast
With a 10 cm circumference of the outer ring (there’s a larger 5-inch variant too), the Mini Titanium Slide Rule provides precise readings through a combination of outer and inner rings. Synchronizing both before use ensures measurement accuracy. For example, to measure a distance, you roll the ruler across the surface and count the number of full revolutions (marked by slight vibrations) while noting the final position of the inner ring relative to the outer scale. Adding these values together gives you the total length, making it a breeze to measure long or curved paths without having to reposition the tool.
No limit to extension length
The slide rule also incorporates simple arithmetic functions. On one side of the tool, you can use logarithmic principles to add values, and on the other, you can multiply. To add two numbers, you find the logarithms of the values on the outer ring, and their sum gives you the result of the addition. Similarly, for multiplication, the rule allows you to calculate the product of two numbers by summing their logarithms and aligning the rings accordingly. While this feature may seem rooted in history, it’s surprisingly intuitive and adds a layer of intellectual engagement that transforms this measuring tool into a small calculating device.
No need to reposition
Crafted from titanium, this slide rule is built to last. Titanium, known for its strength, durability, and resistance to corrosion, ensures that this tool will endure daily wear and tear, making it a perfect companion for outdoor activities or everyday tasks. Weighing only 20 grams, the TITANER is light enough to carry with you wherever you go. Its small size (just 31.8 mm in diameter) and thickness of 5.3 mm make it a discreet yet powerful tool that fits comfortably in your pocket or can be worn as a pendant.
The precision of this ruler is highlighted by its laser-engraved scale, which ensures that measurements are not only easy to read but also resistant to fading over time. Each marking is meticulously etched with high accuracy, providing clear and durable references even after prolonged use. The high processing precision, down to 0.01 mm, guarantees that each rotation is smooth and that measurements remain consistent across multiple uses.
Rolling Ruler
The Role of Ceramic Beads
Beyond its practical applications, the TITANER Mini Slide Rule serves as an excellent everyday carry (EDC) item. Whether you attach it to your keychain, use it as a zipper pull, or simply carry it in its leather pouch, this tool is always at hand for spontaneous measurement tasks. Its sleek, minimalistic design complements its functionality, adding a touch of elegance to your daily gear.
Interestingly, this slide rule isn’t just a precision tool; it’s also a delightful fidget toy. The smooth, rhythmic rotation of the rule, paired with subtle clicks and vibrations, offers a satisfying sensory experience. Much like a spinning top, it provides a calm, meditative activity that can help relieve stress during work or study sessions. This dual functionality as both a tool and a fidget toy makes it an excellent companion for those who enjoy practical, yet playful gadgets.
The TITANER Mini Titanium Curve Measure Slide Rule comes in a few variants. Enthusiasts can either grab the all-titanium variant (which has a slightly higher price owing to the material and manufacturing), or buy a slide rule with an inner ring made of brass (this variant’s distinct dual-color aesthetic has it standing out from the rest). The slide rule comes with a 10-cm circumference, although you can upgrade to a larger version with a 5-inch circumference. All variants rely on a precisely machined structure with an anti-slip texture on the outside, and spring-loaded ceramic beads on the inside that enable the rolling and clicking function.
A masterclass in design, the TITANER Mini Titanium Curve Measure Slide Rule merges functionality with thoughtful engineering. It’s an EDC tool that excels in precision, portability, and durability, while also serving as a unique conversation piece while in use or even worn around your neck as a mark of your creatively aligned profession (sort of like how architects love to show off their mechanical pencils, or fashion designers with their measuring tape always handy). Whether you’re using it to measure unconventional surfaces or simply spinning it between your fingers for a moment of relaxation, this ruler proves that the simplest tools can often be the most innovative.
