The Best Fraction Calculator for Measurement Math
Out now for iOS and Android
Maker Calc is a measurement calculator for anyone who wants to improve their craft.
For woodworkers, metalworkers, leathercrafters, and everyone that uses a tape measure.
"I've been using the app every day while installing cabinets. It helps me resolve complex problems that are really tough to wrap my head around. I seriously love it!"

"I honestly love it. Removing the unused denominators was brilliant. If I need to do some weird fraction math I have other means for that. But the calculations I do daily only involve the standard denominators. That alone makes this my go-to calculator at this point. I use it almost daily in the shop."

“With other apps, its easier to just do the math in my head. But with Maker Calc, it’s worth pulling it out of my pocket to ensure that I got it right.”

Instant Results
Optimized Key Layout
Maker Calc has been very intentionally designed to make equation input dead simple. Whole numbers on the left, fractions on the right.
Additionally, only the essential denominator inputs that you’d find on a standard tape measure are included.
Results as You Type
The absence of an equals sign means that with every value you input, new results are generated. Ensuring you get the results you need as fast as you can type out the numbers from your measuring tape.
Absolute Precision
Rounding Zone
The math you perform won’t always land on a nice even fraction that you’ll find on your tape measure, but you need to have the power to get as close as possible.
Choose your rounding precision and easily grasp where your result falls between the two nearest fractions. Eliminate the guesswork and select the result that best applies to your need.
Precision Adjustment
Adjust your rounding precision in settings is very simple. You can even do it while in the middle of an equation to see the new results.
The Unit You Need
Live Conversions
All of the most relevant conversions are calculated as you type, just like your results.
- Fraction Inch Value
- Decimal Inch Value
- Feet and Inches if greater than 12 inches
- Centimeters
- Millimeters
You can also easily switch your input unit from inches to millimeters if neeeded.

Tapping on the “Live Conversions” area will expand the conversions to make them larger and more prominent.
Never Forget Again
Equation History
Did an equation last thursday but can’t remember all the values? Every time you push AC, your equation and its result gets saved so you can access it whenever you need.
Star and Label past equations
Keep track of the meaningful equations by starring the ones you don’t want to forget. Additionally, you can add labels to better identify what they pertain to.

About Maker Calc
Welcome! I appreciate you being here. My name is Jake Hasler, and making things is my greatest passion. I love woodworking, leatherworking, and anything else that involves building with my hands. I also love building software, and when I couldn't find a great measurement calculator on the app store, I just decided to build my own to dominate all others.
My number one goal with Maker Calc is to help you improve your craft. Precise measurements lead to tight fitting pieces that do your designs the justice they deserve. The use cases are endless, and I want you to have the feeling that you can turn to Maker Calc when you need it most.
I also love heirloom quality tools, especially finding old relics at estate sales, flea markets, or in grandpa's toolbox. The best ones are built like tanks and stand the test of time. I want Maker Calc to give off a similar feeling of quality. As long as I'm still breathing, I will maintain the app and hold it to the highest standard of quality. If there's ever anything about the app that doesn't meet this standard, please let me know and I will fix it as quickly as I can.
There are plenty of other calculators out there that are probably getting the job done for you just fine. I even imagine that the most intelligent and experienced folks may have learned all the tricks to circumvent even needing a calculator. But that's not me -- and even if that's you, I'm certain that just having Maker Calc on your phone will prove valuable.
You can always reach me on instagram @haslercraft.
Thanks,
Jake
