Being intentional with your choice of lead hardness and size will help you use your mechanical pencil more effectively.
A fine point can be difficult to jot notes with, but a thick point can make detailed drawings and line work difficult.
Knowing the difference between kinds of lead and the individual purpose of each will mean you won’t choose the wrong lead again.
Mechanical pencil leads come in such a variety of widths that there is a size for every purpose, from fitting complex equations into tiny spaces to shading broad
swaths of paper. At the same time, the lines they make can change dramatically as the leads wear down or are used at different angles.
Choose the correct diameter of lead. Different mechanical pencils require lead of a certain thickness.
You can usually find this measurement written either on your mechanical pencil itself or its clip.
Because of how thin this lead is, the diameter is typically expressed in millimeters as a decimal, like 0.5 mm, as an example.
0.3 mm diameter is considered to be relatively thin. This size of lead might not be suitable for writing or sketching, but using it you’ll be able to draw with very minute detail.
0.5 mm thick lead is used to be one of the most common sizes of lead. You might use 0.5mm lead for writing or drawing. Overall, it’s still a versatile size that might be just right for your writing needs.
0.7 mm lead is a thicker variety, which makes it suited to sketching and non-detailed work. You may also find this lead useful if you do long-hand drafting. It it also more common nowadays compared to 0.5mm, as cheaper mechanical pencils became more popular using 0.7mm.
0.9 mm lead is an even thicker lead. It can be used with a rather soft lead, and therefore will have less breakage. Good for puzzles on newsprint (crossword, sudoku).
On a scale of the world’s greatest problems, whether or not you’re using the best mechanical pencil and correlating lead isn’t going to make the front page,
but few of us can deny having preferences in this arena. For some of us, the bane is a streaky eraser, while for others, it’s the ultra-sharp lead that seems
to break at the slightest sign of pressure.
In our adult lives, many of us haven’t touched a mechanical pencil in ages, while many others use this implement daily for important job tasks. Alternately,
some of us may want to support our children’s education or hobbies by better understanding which tools will help them get the job done best.
