For example, a 4B would be softer than a 2B and a 3H harder than an H.
Which lead is darker HB or 2b?
Numbers are then used to indicate the degree of softness – the higher the number the softer the lead and the blacker the mark. For example, a 2B lead is softer than a B lead and will produce a blacker mark.

What is a soft lead?
: lead containing virtually no impurities other than the precious metals : lead that has been put through the process of softening.
Which is thicker .5 or .7 lead?
If it’s for school writing, use 0.5mm or 0.7mm leads, depending on which you prefer. The 0.7mm leads are thicker, which is better for people who tend to press hard on the pencil when writing. For drawing,use 0.5mm leads, because they’re more precise than the 0.7mm leads.
Which pencil lead is the softest?
2B, 3B and 4B are increasingly soft. Further up the range, 9B is the very softest lead available, but so soft and crumbly that it’s rarely used. Anything over 4B is probably too soft for most people’s day-to-day use. Harder leads than HB get H ratings.
Is Lead soft or hard?
The softness or hardness refers to the pencil lead. Art and drafting pencils have a range between 9H and 9B. Soft lead usually has a number and the letter B imprinted on it. The higher the number the softer the lead so a 9B pencil has much softer lead than a 2B.

Deciphering the Graphite Pencil Code H pencils are hard and they leave less graphite on the paper. This means that they are lighter. B pencils are softer and leave more graphite on the paper, meaning they are darker. … This means that a 4H pencil is harder than a 2H and therefore also lighter.
