The writing will get increasingly smoother and the lines will get darker.
You’ll know the color is going to be blue, but you don’t expect they will be exactly the same shade of blue.Īs you move from HB up the B scale, you can expect the lead to get softer feeling and smoother as you write. This scenario is similar to the color of a pen - buy a blue pen from Bic and then a blue pen from Paper Mate. This means you can look at the grade on a pencil and know roughly what to expect from it, you just can’t expect it to be exactly the same thing another company would order. Keeping in mind that the grades are not necessarily equivalent from one company to another, they are directionally the same. It’s possible to translate from the American scale to the international one, though grades vary from brand to brand so this isn’t an exact standard. This is why even American manufacturers tend to switch over to the international scale for their artist series pencils. This rating system is clearly less specific than the international scale and while it has persisted through the years, it doesn’t have the same range either. #4 – Very hard pencil used for making sharp lines.The standard pencil for electronic test scoring and the most common pencil grade Lastly, HB is the same as the American standard #2 pencil, the one you are supposed to use for taking standardized tests which are read by scanners.Īs touched on above, pencils made in America have classically used a based on numbers.
Some manufacturers, usually those in Japan, use an “F” for firm, which is similar to an HB, but then will continue with the stacked Bs and Hs. If you think of it as a spectrum you have 10H on one side, HB in the middle, and 10B on the other side. For example 2B is short for BB and it’s a pencil that is more black than a HB but less hard than a 2H. You will see the number of Hs increase as the pencil gets harder and the number of Bs increase as the pencil lead gets blacker.
PENCIL LEAD CODE
Most pencils makes will add a code to the pencil that uses:Ī common, everyday pencil you’d grab from the store is an HB - it’s hard and black in the expected levels.
