Best Thickness Gauges of 2025

"I primarily purchased this to start tying my own tapered flyfishing leaders. I've noticed that while the leader spools indicate the diameter, it can be misleading. For instance, Maxima Ultragreen often measures one to two sizes larger than what's printed. My Rio tippet spools are much more accurate, always less than 0.0005” off. I recommend using a weighted micrometer stand for precise measurements. Overall, this tool feels well-built and meets my needs."

"It's not Mitutoyo, so I didn’t expect that level of accuracy, but for the price, it's surprisingly effective. I even designed a holder for bench use, which makes it much easier to handle. I've found myself using it more often than anticipated."

"This tool works perfectly for my measuring needs. It's easy to operate and comes at a very reasonable price. I'm quite satisfied with the gauge."

"I previously owned one, but it didn't have a small enough size. This one has tons of different sizes, making it useful for a lifetime. They seem accurate, and if you accidentally bend the metal, you can just fold it back, and it naturally straightens out."

"I used it to adjust the valves on my lawn tractor. It worked great, was easy to use and read, and folds into a nice compact form."

"These are good quality and arrived un-oiled, packaged well to prevent any damage. They move smoothly and are perfect for my needs with guitars and basses."

"I find this tool to be super well made and it comes with a nice leather case. If you need to measure wire and metal gauges, you definitely need this. It feels like it will last many lifetimes and is a true one-and-done tool."

"This solid wire gauge measuring tool has been really handy for me while figuring out the gauge of some wires. I can confirm it’s built to last and offers great quality for the cost!"

"Everything was just as described and arrived on time. It's exactly what I needed to measure the thickness of metal."

"I picked up these stainless steel metal sheets welding thickness gauges for my DIY welding projects, and they've been incredibly useful. They're easy to use and provide precise measurements, which is exactly what I needed. The build quality is impressive; they feel durable and can withstand regular use in my workshop. The dual-sided design is a nice touch, allowing me to measure both wire and sheet thickness without switching tools. I've found them to be accurate, helping me achieve better welds by selecting the right materials. They’ve also saved me time by eliminating guesswork and ensuring I use the correct thickness for each project. One minor note is that the numbers can be a bit small to read in low light, but that's easily solved with proper lighting. Overall, I'm very pleased and would recommend them to anyone needing reliable thickness measurements for their projects. They've become an essential part of my toolkit."

"Great value for the money! The easy-to-read markings make it very user-friendly."

"This tool is very useful for measuring small gauge wire. It feels sturdy and is well made. I just didn't realize how much I would use it until I got it; now I don't know how I managed without it. It's really handy. I used to rely on a micrometer to measure and then look up wire sizes, but not anymore!"

"I purchased this as a backup for my expensive ultrasonic meter used to measure the thickness of a steel boat. It works great, is easy to calibrate, and the menus are intuitive. I tested it on 1mm aluminum and it was spot on. What a deal!"

"With 10 years of NDT experience, I bought this for contract weld inspection work. I measured a 4" X52 pipe and it confirmed my expectation of .237W thickness. The readings matched those from the NDT company. I'm really impressed with its performance for the price!"

"I bought this ultrasonic thickness gauge because the one we use at my concrete company often gets misplaced or locked away. This one works even better than the more expensive model we have, so now I can do my job without interruptions!"

“This tool works perfectly for my job. I can get the right measurements and order the materials accurately. Its compact design makes it easy to carry around. I mostly recommend it!”

“I think the quality seems great for the price, and I can't wait to start using it.”

“Functionally, it works fine, but the sheet thickness gauge was smaller than I expected, and the lettering is hard to read for my older eyes.”

"This device might not be the most precise, but it performs its function flawlessly. I have absolutely no complaints about how it works, and it's definitely worth the price. With a backlight and standard battery power, it's a major improvement!"

"I found the Paint Thickness Meter CM-205FN to be a great value for the price. I've used it on several cars and got pretty good measurements."

"Initially, I wasn't sure how to calibrate it, but the seller was very helpful. Fortunately, the device was accurately calibrated from the factory and even has a ‘Reset’ button to restore default settings. It's perfect for measuring car paint!"

"I've found the Paint Thickness Gauge TC100 to be an incredibly helpful tool when checking the condition of car paint, especially for used vehicles. It's straightforward to operate and gives me quick, accurate readings that boost my confidence in evaluating a car's original coating."

"I was pleasantly surprised by how easy it is to calibrate and use on various metals. I would definitely recommend this tool to anyone!"

"As someone who buys cars regularly, I can say this tool is essential. It allows me to quickly identify any bondo or repaint, making my evaluations much easier."

“To be honest, I thought I was getting a sheet metal thickness gauge. I'm not sure what to do with a wet film depth gauge. I don’t paint much, so it's not very important for me.”

“When I measured the gauge with calipers, some measurements matched the label perfectly, while others were off by 1 mil—like my 24 measuring 25. This is acceptable considering tool and user error. Overall, it's usable and comes in a small sleeve to keep it safe. This particular comb seems similar to others that come in multi-packs at a comparable price, so the value really depends on the buyer.”

“I've been very happy with my purchase and the low cost! It's perfect for my application in sales.”

“I've used this digital micrometer extensively for about 15 months, taking between 10,000 to 12,000 measurements. I found that it works best when secured to a lab stand, as it tends to lose zero after repeated use but always returns stable. It’s excellent for rapid repeat measurements.”

“This Mxmoonfree Digital Thickness Gauge is very accurate and reasonably priced. I compared it with some pro-grade calipers that cost 10 times more, and it performed similarly to the 4th decimal tolerance. I really appreciate the handle design and the tea pot style lever.”
