Black Diamond on Measuring Tape: What Is Its Function?


When you look closely at your measuring tape, you will usually notice black colored diamonds. You may have always wondered what these are, or you may not have noticed these black diamonds before. Of course, unless you use a measuring tape daily, it is natural that you never notice these small and black, diamond-shaped markers. However, it is not difficult to give a good guess as to what they might mean, as these markers are on a measuring tape. Black diamonds, as they are commonly called, are sometimes called black circles and are stud or beam markings.

These small black diamond shapes are not featured on a measuring tape for decoration purposes and that’s why they have a function and are very helpful. Together with the red boxes and the black boxes around the numbers, these black diamonds have a function of facilitating things for people like construction workers and self-employed people. Black diamonds have a similar function to the red boxes on a tape measure showing the most common distance between posts in homes and traditional buildings (16 inches apart). These 24-inch spaced black diamonds are for overlays in buildings in smaller buildings (such as hangars) where the weight load is lighter and allows the marking lines for stud to work quickly.



Although not included on all tapes, stud marks generally are at 16″ intervals and joist marks are at 19.2″ intervals. The center of one stud is usually positioned 16 inches from the center of the stud before it, and naturally 16″ stud mark. On the other hand, joists, are generally 19.2″ inches apart from the center of the joist in front While this may seem like a rather odd measurement, many American building materials such as ride-on rides, etc. typically come in 8ft lengths and 19.2″ is divided into 8 ft perfectly, in other words, 5 times.

These black diamonds can assist you when remodeling your home, hanging something heavy, or fixing a piece of furniture. There should be six posts spaced 16 inches apart for every 8-foot section of your wall. So, using black diamonds, you can find studs all over your home and hang pictures of the studs.

How Black Diamonds on Measuring Tape Work?

If you have ever used a measuring tape before, you have most likely noticed the little black diamonds that are quite distinct. Whether you are making a bookcase, measuring a wall for a new sofa, or trying to hang your photos straight, you will certainly need a measuring tape for all of these processes. Most homeowners have at least one of these yellow god feasts somewhere in their toolbox or workshop drawers. Even the newest builder has the concept of “measuring tape”.

Of course, there are not only diamond shapes on a standard measuring tape reel, and there are several different types of markers. The measuring tape that you will use will tell you inches and feet and sometimes meters/centimeters and if you are not professional, you probably have not used them much yet. Still, some of these marks will be useful, especially if you are working on a heavier job, but there is a small mark on the measuring tape that most people ignore a manufacturer design. 



These markers are in the shape of “black diamonds”.

Black diamonds are symbols used to indicate the central area between the pillars in a house or building, and the symbol will always be placed in the 19.2-inch mark. However, to use these black diamond symbols to their full functionality, you should first take the time to understand the “8-foot rule”.

Many measuring tapes add red numbers or some other graphical feature every 16 inches and a very common gap for studs in the house frame. For this reason, there are red numbers highlighted every 16 inches. If you are using measuring tape, you can determine exactly where the studs are by using the red numbers and marking the studs with a pencil. At this stage, black diamonds come into play and represent the middle of the studs.

The black diamond starting at the 19.2-inch mark helps you find the center of the first stud, and the next black diamond is 19.2 inches from the first stud or 38.4 inches from the beginning of the tape measure and the diamonds extend to the 96-inch mark or 8 feet. You should be able to easily find the center of the five studs, not counting the stud at the beginning of the measuring tape. That way, put your stud finder aside because you have already found your studs.

Black diamonds that appear every 19 3/16 inches on metal measuring tapes are for determining the I-beam “lumber” spacing. Several wood product manufacturers offer I-beam “lumber” instead of solid lumber deck joists. The diamond markings on the strip ruler blades are for spacing these engineered floor beams in the new structure, and because these beams can support more weight than their dimensional lumber counterparts, there are often different spacing requirements.

Span tables for these beams provide ratings for 12 “, 16”, 19 3/16 “and 24” spacings, and if you multiply these dimensions by 8, 6, 5, and 4, each is 96 “, which is the length of the plywood panels used for the subfloor. These diamond marks are intended for builders who want to exploit the great strength of I-beams designed using fewer ground beams without losing the ground support. For these beams, span tables provide ratings for 12 “, 16”, 19 3/16 “and 24” spacings. Multiply these dimensions by 8, 6, 5, and 4 respectively, and each will turn out to be 96 ”, the length of the plywood panels used for the subfloor.



A concrete block chimney consists of two bricks by two bricks or roughly 16 inches square. Since there is only 14-1 / 2 “between studs, this chimney will not fit between studs attached to 16” centers. However, the “Black Diamond Gap” is ideal as the spacing between studs in this range is 17.7 inches.

Where Black Diamonds On Measuring Tape Are Used?

We mentioned that the black diamonds on the measuring tape represent spacing, the first black diamond is at 19.2″ and after that, black diamonds appear at 38.4″, 57.6″, 76.8″ and 96″, or 8-feet. This is a seamless stud that counts the starting and ending studs for every 8 feet of a wall. Instead of breaking this bulky stud detector, if you know your walls are built according to this standard stud placement formula, you can simply use your measuring tape to find them. It is pretty clear they are not just for decoration but you probably have no idea what they are for.



The black diamond marker on a measuring tape is between 16 inches and 24 inches apart, and these markers are often used in concrete block chimney construction. However, of course, these markers have other uses as well. Marked at 19.2 inches apart, the use of this type of layout allows for a greater weight load with fewer pieces of wood. This can save money, but may not follow building codes in all areas. If you do not plan to build a house, you can still use these numbers to build a solid shed or find studs in your house wall.

The diamond markers exist for builders looking to take advantage of the enormous power of I-beams designed using fewer ground beams without loss of ground support as code allows. Builders generally sit above the numbers, positioned within the line indicating one-inch segments. They are used by people who make their living in construction, according to construction.

This is why those who earn money for a building need measuring tape a little deeper than those who take them out to check our height. Black diamonds are called “trust marks”. These are also known as stud or joist marks. A truss is a frame that usually refers to beams, posts, and struts and supports a building. In other words, these innocuous little signs help professionals with lattice layouts. That is, it speeds up the process of predicting where each part of everything you aim to lay should go.



Plywood and particle board are spaced 16 inches or 19.2 inches apart because this is the most common of the floorboards. This is not the only head, either, and your measuring tape also includes Roman numerals. They tend to be hidden in a circle at the very beginning of the measure, so you will see it as soon as you take it out of the vault. They show how correct a measure is and therefore can be said to be quite important.

Diamond markers are a visual mark designed to make the work faster. Joints are used to starting the frame, and each sub-floor panel has 5 additional joists and open partitions. The measuring tape also includes markings that should assist you when it comes time to insert the wall studs. Yet, this topic is another story for another day

Black diamonds provide the help that you need for your floor joists. This provides the necessary space that you need when it comes time to make changes to the subfloor. Rim boards and joists are required to start the frame although the measuring tape measure is even more important. Consequently, without the small black diamonds on measuring tape, the work process does not go as quickly. Getting the right spacing is hardly easy when working without a measuring tape that has not diamond markers.



What Is Black Diamond Stone?

Just as there are black diamonds on the measuring tapes, there are black diamonds in real. So what are black diamonds, an important indicator of tape measuring, in reality? This question sounds simple, but in fact, the term black diamond can refer to several different types of stone.

Natural black diamonds also called “fancy black diamonds”, take their color from nature. During the formation of the diamond on the earth, other minerals are trapped in the diamond and the extremely high amount of these other minerals in the diamond is the reason why natural black diamonds are black. You can get help from the clarity chart for information on inclusions. The great thing about inclusions is that these are the things that give the diamond its unique character and make it different from other gems by the fact that the two diamonds do not have the same inclusions.



Carbonado is a naturally occurring rock material but are only found in Brazil and Central Africa. Geophysicists consider these stones to come from a meteorite and believe they are made of carbon, graphite, and diamond. Black diamonds note that they are not “natural” or “fancy”, are found in nature even if they are not in color. These diamonds are sometimes referred to as “treated black diamonds”. 

Black colored diamonds or color enhanced diamonds turn black with heating processes that typically turn out colors from dark gray to black. Laboratory-created black diamonds are the same as natural diamonds but they are not stone and their colors are not found in nature because they are lab-grown. 



Are Black Diamonds Real?

Yes, black diamonds are real diamonds. Natural diamonds, Carbonados, and black diamonds are found in nature, but unlike natural diamonds and Carbonados, black diamonds are not naturally black and are heat-treated to achieve this color. However, laboratory-grown black diamonds are man-made; that is, they are not removed from the ground like other diamonds. Although it is the same as mineral diamonds in terms of structure and chemistry, neither the color of the stone nor the stone comes from nature.


Black Carbonado Diamond

The cost of a black diamond is determined by both origin and size. However, fancy black diamonds and Carbonados are very rare and only one out of 10,000 natural diamonds is a colored diamond. Natural black diamonds and Carbonados are some of the most valuable and costly due to their rarity. Many black diamonds are available by heat treatment and are therefore naturally more economical than black diamonds. However, keep in mind that sometimes heat-treating a stone can cause it to weaken, and therefore heat-treated black diamonds may be less durable than natural black diamonds.

Naturally, black diamonds created in the laboratory are also cheaper than their mining counterparts. They are as durable as natural diamonds, as they are grown with the color they already contain, and regardless of their origin, the value of a black diamond is based on the same criteria as all diamonds. These criteria are 4C characteristics such as clarity, cut, color, and carat. Unlike colorless diamonds, the clarity for black diamonds depends on the external conditions of the stone. On the other hand, like any other diamond, the higher the carat weight of black diamonds, the higher the price.
