Is a 0.5 mm or a 0.7 mm Pen Better?

If you’re out shopping for office supplies and you need to get more pens, you may notice that there are options for the size tip you can get on a pen. Two of the most common sizes are 0.5 mm and 0.7 mm, but which one is better?

Determining which size pen tip is better is all down to personal preference, but most people tend to favor 0. 7mm pens over 0.5 mm pens because the tip is a bit larger, so it creates slightly thicker lines. 0.7 mm pens also do not require as much pressure to be applied to the tip for the ink to flow out.

In this article, we will review the preferred uses for 0.5 mm and 0.7 mm pens as well as what kinds of pens are available in 0.5 mm and 0.7 mm tips. As a bonus, we will recommend the best 0.5 mm and 0.7 mm pens on the market.

What Are 0.5 mm Pens Better For?

Although 0.5 mm pens have thinner tips than 0.7 mm pens, they are usually preferred by artists. For artists who appreciate a light touch and need to add fine details to their work, 0.5 mm pens are usually one of the best tools to use. Calligraphers and those who artistically design the written word also prefer 0.5 mm pens.

0.5 mm pens are better for people who have a lighter touch. Those who are heavy-handed in their writing can easily break the tip or cause the ink to bleed. On the other hand, those who have a light hand appreciate that there is little pressure required to get the ink to flow from a 0.5 mm pen.

What Are 0.7 mm Pens Better For?

What Kind of Pens Come in 0.5 mm?

Gel pens and rollerball pens typically come in 0.5 mm tips. Because of the nature of the ink, the 0.5 mm tip allows the gel pen to glide smoothly over the paper for a thin line effect. Rollerball pens are also ideal for making fine-tipped strokes with a 0.5 mm pen.

They are usually available as retractable tips because the finer tip can be easily damaged if a cap is replaced too aggressively. Although there are capped options for 0.5 mm pens, you just need to be extremely careful that you don’t break the tip and always replace the cap when not in use.

What Kind of Pens Come in 0.7 mm?
