All great things are round. The sun and moon, the metaphorical circle of life, pizza, cake, CDs, the iPod wheel, and the Titaner Curved Titanium Measuring Ruler. Sure, that premise sounds a bit grandiose, but this humble little ring-shaped device goes far beyond a simple rolling scale. Made from a combination of titanium and copper, the Curved Titanium Measuring Ruler can measure linear and nonlinear distances (in multiple units), but it can also add (or subtract) and even multiply using basic logarithmic principles. In short, this little handheld device is a fixture of an alternate reality, capable of doing multiple things in a form factor that mainstream gadgets haven’t explored before. The bonus? It also doubles as a fidget toy, making it perfect for everyday use by creatives.

At first glance, this sliding ruler stands out with its elegant circular shape. Unlike traditional straight rulers, TITANER’s circular, pivotless design allows for continuous measurements on any surface, whether flat or curved. Its circular design removes the limitations of a fixed linear ruler, providing limitless possibilities for measuring longer lengths simply by sliding it across a surface. This continuous ring system is what sets TITANER apart, making it a versatile tool for designers, engineers, and DIYers who often need to measure odd shapes and sizes without being restricted by scales and tape measures.
Quickly measure irregular shapes
With a 10cm outer ring circumference (a larger 5″ version is also available), the Mini Titanium slide ruler provides accurate readings through a combination of outer and inner rings. Synchronizing both before use ensures accurate measurements. For example, to measure a distance, you can slide the ruler across the surface and count the number of complete turns (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 easy to measure long or curved paths without having to reposition the tool.
There is no limit to the length of the extension.
The slide rule also includes 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. Similarly, for multiplication, the rule allows you to calculate the product of two numbers by adding their logarithms and aligning the rings accordingly. While this feature may seem rooted in history, it is surprisingly intuitive and adds a layer of intellectual engagement that turns this measuring tool into a mini calculating device.
No need to reset
Made from titanium, this calculator ruler is built to last. Known for its strength, durability, and corrosion resistance, titanium ensures that this tool will withstand everyday wear and tear, making it the perfect companion for outdoor activities or everyday tasks. Weighing just 20 grams, the TITANER is light enough to carry with you wherever you go. Its small size (just 31.8mm in diameter) and 5.3mm thickness make it a discreet yet powerful tool that fits comfortably in your pocket or can be worn as a necklace.
This ruler features high precision thanks to its laser-engraved scale, ensuring easy reading of measurements and resistance to fading over time. Each marking is engraved with high precision, providing clear and permanent references even after long-term use. High machining accuracy, up to 0.01mm, ensures that each turn is smooth and measurements remain consistent over multiple uses.
Rotary ruler
The role of ceramic beads
In addition to its practical applications, the TITANER Mini Slide Rule also serves as an excellent everyday carry tool. 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 on hand for spontaneous measuring tasks. Its sleek, minimalist design complements its function, adding a touch of elegance to your everyday gear.
Interestingly, this calculator ruler is not just a precision tool; it is also a fun toy. The smooth, rhythmic rotation of the ruler, coupled with subtle clicks and vibrations, provides a satisfying sensory experience. Just like a turntable toy, it provides a calming, meditative activity that can help relieve stress during work or study sessions. This dual function as both a tool and a fun toy makes it an excellent companion for those who enjoy tools that are both practical and fun.
The TITANER Mini Titanium Curve comes in several versions. Fans of this type can either buy the all-titanium version (which is a bit more expensive due to the material and workmanship), or opt for a sliding ruler with a brass inner ring (this one has a distinctive two-tone aesthetic that makes it stand out from the rest). The sliding ruler comes in a 10-inch diameter, though you can upgrade to a larger 5-inch version. All versions feature a precision machined construction with an anti-slip texture on the outside, and spring-loaded ceramic beads on the inside that enable twist and click functionality.
The TITANER Mini Titanium Curve Slide Rule is a design tool that combines functionality with thoughtful engineering. It’s an EDC tool that’s precise, portable, and durable, but it also doubles as a unique conversation piece while in use or even worn around your neck as a sign of your creative profession (much like architects love to show off their mechanical pencils, or fashion designers always use a tape measure). Whether you use it to measure unconventional surfaces or simply twirl it between your fingers for a moment of relaxation, this ruler proves that the simplest tools can often be the most innovative.
