Why are number 2 pencils required?

No. 2 pencils were required to fill in the circles on the sheet because the graphite in the pencil is an opaque substance that absorbs the light that hits it. Most modern sheets are now read by machines that measure lightness and darkness. These machines (technically) do not require the use of No.

What is a #3 pencil?

Today, many U.S. companies use a numbering system for general purpose, writing pencils that specifies how hard the lead is. 1 pencils, HB = No. 2, F = No. 2½, H = No. 3, and 2H = No.

What is a HB pencil best for?

For simple sketching, the HB pencil is probably the most popular, with artists also favoring the H and the B pencils. For preliminary sketches that will be used as a guide for a painting or illustration, the lighter 2H–4H pencils are ideal.

What are HB pencils used for?

HB is Medium Hard and is commonly used for writing. If a Pencil is graded B it is softer than an HB grade and if it is graded H it is harder than an HB pencil. the Numbers next to the Letter just mean how soft or hard the Pencil is.

What do the numbers mean on a pencil scale?

The numbers indicate degree of hardness or blackness, so 8H is harder than 7H, for example. The black end of the scale is popular for sketching, the hard end for drafting. In the middle of the scale are the grades corresponding to the number grades for inexpensive writing pencils: B = #1, HB = #2, F = #2.5, H = #3 and 2H = #4.

Are A1 pencils good for sketching?

A #1 pencil is hard and produces sharp lines, it’s good not only for detailed sketching and illustration, but for detailed writing, especially like formulas and accounting. The #3 and #4 pencils are softer leads and are good for creating dark lines, and heavy dark shading. As well as good for tracing.

What is the hardness of pencils?

The hardness scale for pencils works like a number line with F and HB being dead centre. On the B side of the scale as it goes up the pencils get softer, meaning they have more graphite than binder in them, when you get up around 9B you have pretty much dead soft pure graphite.
