Mechanical pencils come in different point sizes, and choosing the right one makes a real difference in how your writing looks and feels. The BIC Xtra Smooth Mechanical Pencil in 0.7 mm medium point is the most common choice for students and everyday writers, but it helps to understand why and whether it's the right fit for you.

What Does 0.7 mm Medium Point Actually Mean

The number refers to the width of the graphite lead inside the pencil. A 0.7 mm point produces a line that's neither too thin nor too thick, making it the standard for most schoolwork, note-taking, and standardized tests. When you look at a mechanical pencil, you'll see this number printed on the barrel or packaging, often written as "0.7 mm" or simply "0.7."

Other common sizes exist. Thinner points like 0.5 mm create finer lines and are popular with people who prefer precise handwriting or technical drawing. Thicker points like 0.9 mm produce bolder marks and work well for people with larger handwriting or those who prefer heavier pressure. The 0.7 mm medium point splits the difference, which is why it became the standard in classrooms across the country.

When a 0.7 mm Medium Point Works Best

This size suits most everyday writing situations. If you're taking lecture notes, writing essays, completing homework, or preparing for tests, the 0.7 mm width gives you enough visibility without being so thick that it looks childish. Teachers and standardized testing boards settled on this size because it reads clearly, allows reasonable writing speed, and works for most hand sizes and writing styles.

The medium point is particularly good if you switch between cursive and print, or if you're left-handed. A common concern with mechanical pencils is smudging, especially for left-handed writers whose hand drags across fresh graphite. The BIC Xtra Smooth Mechanical Pencil uses smudge-resistant lead that dries quickly and erases cleanly without leaving gray shadows on the page, which helps protect your finished work regardless of which hand you write with.

Understanding the 40-Count Pack and Refillability

A 40-count pack contains 40 individual pencils, sized for stocking a backpack and lasting through a full school year or for filling a classroom supply drawer. This quantity makes sense because even though mechanical pencils are refillable, you'll likely want multiple pencils in different locations—one at home, one in your bag, one in a pencil case at school.

The BIC Xtra Smooth Mechanical Pencil is refillable, meaning you can replace just the lead and eraser when they wear out instead of throwing away the entire pencil. Lead refills are inexpensive and widely available. To refill, twist or unscrew the barrel according to the pencil's design, remove the spent lead cartridge, and insert a new one. This refillability extends the value of each pencil well beyond its initial graphite supply.

Lead and Eraser Maintenance

Mechanical pencil lead breaks more easily than you might expect, especially during the first week of use. If the tip snaps, simply click the advance button (the top of the pencil) to extend fresh lead. Keep the pencil in a protected space like a pencil case rather than loose in a backpack where pressure can shatter the delicate graphite inside.

The built-in eraser at the end of the BIC Xtra Smooth Mechanical Pencil erases the smudge-resistant lead cleanly. As with the lead, the eraser depletes over time and can be replaced when it wears down. You'll know the lead needs replacing when you have to click more and more times to advance any material, and the eraser needs replacing when it no longer removes marks effectively.

Is 0.7 mm Right for You

If you've never used a mechanical pencil before, 0.7 mm is the safest starting point. Standard notebooks, test forms, and grading rubrics all assume this point size. If you find your handwriting feels too large or too small with a 0.7 mm point after a few weeks of use, then you might experiment with a different size. But for most people, the medium point works because it matches what's expected in academic and professional settings.

The BIC Xtra Smooth Mechanical Pencil, 0.7 mm medium point, remains a reliable choice for this reason—it's built around what actually works for the majority of writers.
