Hello this is Nick. I have a question please if I can help me. Is this good for drawing w pencil. My other ruler from art store leaves those small smudges from markings of measurements as I moved it when I draw buildings or houses with perspective Ty

Answer This Question

Hi . This ruler is made of stainless steel and has etched black graduations. This means the markings are engraved into the material, not printed on top, so they won't smudge when you move the ruler while drawing. It's designed to be durable and accurate, which should be helpful for perspective drawings of buildings and houses.

How wide is the ruler? Is it exactly 1 inch? The description says 2 1/8? but it is obviously wrong looking at the photo.

Answer This Question

The assembled width of the ruler is 2.125 inches. This is equivalent to 2 1/8 inches.

By|Jul 11, 2026

This ruler is indeed 1" wide. It would not even make sense for a 6" long ruler to be 2-1/8" wide.

      It is 1 1/4" wide and 18" long. I bought it to use as a straight edge to cut my Christmas fudge with. Does exactly what I wanted it for! Now instead of having all different sized pieces of fudge, they are all the same size!

          Not straight
          I bought this to check cylinder heads for warpage. Unfortunately the ruler is not precisely straight. It gives different indications depending on which edge I try to measure with. If you need to check straightness by sliding a feeler gauge under the straight edge, this ruler will NOT do the job.

            Zero isn't the end of the ruler
            The markings of the ruler dont start at the end of the ruler. This means you cannot hold the end against somethings and measure it. The ruler doesn’t even start a simple distance from the end. It’s more than an 1/8” but less than 1/4”. For woodworking or metalworking this thing is useless. If i hadn’t gotten it as a gift i would return it. Now it will sit in my tool chest collecting dust. I ish i could give it less than 1 star

              I needed an 18" straight edge to check the relief on my guitar neck while I adjusted the action. I looked in several stores and was about to give up finding what I was looking for. Then I thought I would try Home Depot and I found exactly what I needed. The ruler was the right length and weight and allowed me to determine the relief on the neck was where I wanted it to be.

              A good sized ruler with multiple scales...good for the shop
              Sometimes my tape measure is not the right measuring tool - particularly for certain woodworking projects. A ruler works better. This 18-inch ruler is a good size for projects that require precision. I have found that 12-inch rulers are generally not long enough and anything plastic will either bend or get nicked and then quickly become useless. This ruler solves the problem. 1. The markings do not start at the end, so you are sure that the first inch of the ruler is a full inch, and not worn down or cut just a hair short 2. There are two sets of scales, plus metric: 1/16" on one side, 1/32" on the other and MM on both sides 3. Stiff, but still flexible The only thing to note is that this ruler is stiff, not rigid. It is slightly flexible even though it is made of stainless steel.

              Dual scales. Markings don't start at edge.
              HD Store SKU # 504309. The ruler markings start about 1/8" from the left end. On the front the top scale is in 32nds and the bottom scale is in millimeters that has stamped 10, 20, ... 450. On the back the top scale is in 16ths and the bottom is in millimeters. The only thing I'm worried about is if this "stainless" steel rulers can corrode. I'm using it for photo mats. It is made in India and inspected in the USA.

              Ruler is fine. Trip to Home Depot - Oakland #1007 was not. Actually wanted to buy a pressure washer, but given local shrinkage, everything of value is locked up with no staff to unlock items for customers. I gave up after 40 minutes of waiting, having asked employees in other depts 3 times for help (resulting in overhead announcements to no effect). This ruler was a consolation prize.
