Pencil Grades from H to B, in Plain Terms
What H and B pencil grades mean, which few grades are worth carrying, and how pressure changes the mark.
Pencil grades run from H towards harder and lighter, and from B towards softer and darker. HB sits in the middle and is what most people were given at school. The scale is a useful code and a terrible shopping list. You can draw well with two grades. Owning every number from 9H to 9B does not fill a sketchbook.
What the letters are doing
An H pencil has a harder lead. It holds a fine point and leaves a pale line that is harder to erase if you press. It suits a light construction drawing you do not want to dominate the page. A B pencil is softer, darker, and wears down faster. 2B is a general sketching grade. 4B and 6B give you a dark you can see from across the room, and they smudge if your hand follows the line.
The same grade from two makers will not match exactly. Test on your paper. Paper Weight and Tooth: What the Numbers Mean changes the mark as much as the grade does. A 2B on rough paper looks grainy and dark. The same 2B on a hot-pressed sheet looks smoother and lighter.
Pressure is the other grade
One pencil can make a pale line and a darker line if you change pressure. Beginners buy a new grade instead of leaning. Try a value strip with a single 2B, from a whisper to a firm stroke, before you decide the pencil cannot reach. You will still want a softer grade for a true black, because pressing a hard pencil until it is dark grooves the paper.
That groove is the giveaway. If the page is embossed, you used pressure as a substitute for a softer lead, or you drew on too hard a sheet. Keeping Sketchbook Pages Flat and Unsmudged is the follow-on once the soft grades enter the book. They need a scrap under the wrist.
A small set with jobs
A fair kit is HB or H for placing a shape lightly, 2B for the drawing, and 4B or 6B for the darkest accents. Name the jobs so you do not shade an entire study in 6B and then wonder why it smeared into a single grey. A Pocket Kit: Few Tools, Useful Pages should contain one of these, not the tin. Carry the 2B. Leave the rest by the table.
Mechanical pencils are convenient and usually limited to a narrow range of grades and a thin line. They are excellent for notes and poor for a broad dark. A wooden pencil you can sharpen to a point or wear to a chisel is more versatile. Sharpen it. A blunt soft pencil makes a fuzzy mark people blame on their talent.
A sheet that tells the truth
On one page, label HB, 2B and 6B and make a short gradient with each. Keep that page. When a drawing is too pale, you will know whether to press the 2B or pick up the 6B. When a drawing is scratchy, you will see that the H was the wrong tool for a shadow.
A Ten-Minute Daily Sketch Routine You Can Actually Keep does not require a grade discussion in the middle of it. Decide the pencil before the timer starts. Changing tools every minute is how a short study becomes a rummage.
Frequently asked questions
Is HB too hard for sketching? It is fine for light drawings and for planning. For a page with real darks, it will tempt you to gouge. Pair it with a B grade rather than abandoning it.
What about F? F sits near HB, a little firmer. You do not need it if you already have HB. The letters are a ladder, not a collection to complete.
Do grades work the same in coloured pencils? No. Coloured pencils have their own cores. Do not expect a code of H and B on them. Test those separately, on the same paper.
Steps
- Test a short range: Make a swatch of HB, 2B and 4B or 6B on the paper you actually use.
- Assign each grade a job: Use the harder pencil for light construction and a softer one for the darkest notes.
- Leave the rest in the drawer: Add another grade only when a drawing fails for lack of a lighter or darker mark.
