Can You Put Any Size Lead in a Mechanical Pencil?

Mechanical pencils are a wonderful creation so far for their immense skill and professionalism. Therefore, curiosity about mechanical pencils, the lead sizes they can carry, and other things grow automatically.

Similarly, people ask questions like – can you put any size lead in a mechanical pencil? There is actually no straight answer to this question.

There are some mechanical pencils that come with adjustment settings but most traditional mechanical pencils will not allow you to use any size lead.

Can You Put Any Size Lead in a Mechanical Pencil?

Mostly, no. It’s because the lead diameter of a mechanical pencil varies from the other. And that’s why you cannot fit a thicker-sized lead diameter into a thinner one.

But there is a little bit of chance that you can place your thin lead diameter into a thicker one, though this will give you an uncomfortable way of writing experience. Even though, the hardness of lead does not matter in this case. You can use any 2B, 2H, or HB lead hardness in any mechanical pencil.

Can You Use 0.7 Lead in a 0.5 Pencil?

Between o.5mm lead size pencil and a 0.7mm lead size pencil, there are some certain differences. These differences will surely not allow the 0.7mm one to fit into a 0.5mm lead-size pencil. The basic reason for this is that the latter one is thinner than the former one.

Basically, 0.5mm lead-size mechanical pencils are very precise and most people prefer them because of their comfortable size. Besides, they offer very fine consistency in the trail. As a standard size, you will find hardly any flaw in this 0.5mm lead-size mechanical pencil.

However, 0.7mm lead-size mechanical pencils are also known as standard-size mechanical pencils. Many manufacturers started to adopt this size and manufacture pencils with 0.7mm diameter. It’s because they provide clearness to a great extent.

But you can tell easily that the 0.7mm diameter lead size is thicker than the 0.5mm lead size. That’s why it is difficult to put this size into your thin-sized pencil. You might create damage to your mechanical pencil in the process, so you better find the right one for your 0.7 lead pencil.

Can You Use 0.9 Lead in a 0.7 Pencil?

If you want to make your best mechanical pencil useful and try fitting your 0.9mm lead size into a 0.7mm lead size, things will not work. It’s because your 0.7mm lead size mechanical pencil is made in such a way that you can only have a 0.7mm lead into it properly.

If you want a 0.9mm lead in a mechanical pencil, then you just have to buy a pencil that has a diameter of this size. You don’t have to destroy your present one by experimenting or forcing it to adopt a thicker lead size than it can adopt.

Besides, you should have a 0.9mm diameter lead-size mechanical pencil. The thickness of this lead size is very traditional as traditionally many people like its fluid trail. It almost gives a vibe of a general ballpoint pen. From drawing to making straight lines to writing professionally, 0.9mm lead pencils are great to use. So, having a 0.9mm lead-size mechanical pencil will definitely benefit you and will enrich your study arsenal.

Can You Use 0.3 Lead in a 0.5 Pencil?

Well, a 0.3 lead comes with a very thin and minimal size. With its low-key size, you need to handle it properly because this particular size happens to break down easily. You need to treat it with tenderness. People who work with graph papers are in need of leads of this size. The pencil with which the 0.3mm leads come also has to have a diameter of proper size.

That’s why it’s very unlikely to put your 0.3mm lead into a 0.5mm size pencil diameter. The thinness of 0.3 lead will not allow it to fit into the diameter and even though you manage to fit it in that diameter, the lead will break down in a single or double use.

It’s because this thin size of the lead cannot just stand the pressure of the pencil and thus you will be wasting your money, time, and energy in enforcing your 0.3mm size lead into a 0.5mm pencil. If you have to do technical drawings, straight line drawings, and other types of detailed works, then just have a mechanical pencil that has a 0.3 diameter in it.

Is 0.3 or 0.5 Lead Better?

Both 0.3mm and 0.5mm leads are good as they are capable of serving their own kind of purpose. Manufacturers make both these sizes leads so people can buy according to their needs. Even though their quality depends on the demands of people and each varies from the other, they have physical differences.

A 0.3mm lead is very thin, in fact, the thinnest in the world of several sizes of lead. Because they are thin, they might seem fragile to some extent. Too much pressure while writing with this lead size might actually cause them to break down. That’s why they are a little bit less popular.

But the good thing is you can get the harder version of 0.3mm leads too. They even come in HB, so, they will not give you much trouble. Basically, for detailed works in graph papers where you might have to give several straight thin lines. However, another downside of 0.3mm leads is that their HB versions might give you hard time controlling as they are not good with curving.

On the other hand, 0.5mm leads are thicker than 0.3mm ones. For this thickness, they are very popular and most manufacturers manufacture pencils for this 0.5mm lead size to a great extent. You can use this thick lead for both writing purpose and drawing purposes.

They might not be able to give you finer detail like the 0.3mm one but you can make them work in other technical drawings. Also, this lead size is harder than 0.3mm leads. But as we have already said that both sizes are useful for different useful purposes. So, undermining any of the leads will be an unwise job. You better pick both of them and make them work purposefully.

Should I Use 0.7 or 0.9 Pencil Lead?

It totally depends on your choice whether you should adopt the 0.7mm lead or 0.9mm lead. It’s because both give you nice consistency in the trail and their hard texture will allow you to write with less effort. Also, you don’t have to be conscious all the time thinking they can break down anytime because both these leads are pretty hard to break easily.

Yet, they differ from each other in the aspect of hardness and also thickness. Definitely, the 0.9mm leads are harder and thicker than the 0.7mm leads. Besides these differences, there are some more. Many manufacturers are adopting the 0.7mm lead size as the standard size for mechanical pencils.

On the other hand, 0.9mm leads have traditional customers. Since the 19^th century, these 0.9mm leads are famous. From writing to drawing, people used to use this lead size to the greatest extent. People still prefer this size for they provide a feeling that we get with a pointed pen. This 0.9mm lead offers solid lines and a clear view to the writer and reader. For sketching, it excels for sure.

0.7mm leads, in this case, also offer a great deal. It matches the vibe of a rollerball. Besides, their hardness and perfect thickness make them one of the best kinds. For day-to-day writing, this lead is top-notch. You can also allow them to do some of your detailed works of technical drawings and make them work for sketching without any second thought.

What Size Mechanical Pencil Lead Is Best?

This question actually depends on the comfort of people. Basically, we see most people adopting the 0.5mm lead pencil for their first-time experience in writing.

This size is pretty much convincing as it has thickness and hardness. But for heavy-handed people, 0.5mm pencils fall short because they tend to break down. So, for normal-handed people who give light strokes while writing can adopt this 0.5mm mechanical pencil easily.

But if you want a more clear view of your writing, like it is popping out from your writing script, you can look for 0.7mm mechanical pencils. They are just fine for everyday writing, sketching, and technical drawings more or less. So, adopting them will not be a bad decision.

Then again, if you want a solid texture for your writing and more thickness and hardness of the lead, then you can adopt 0.9mm mechanical pencils. This size ensures more solidity and toughness of the lead, so you can use it a little bit recklessly.

Final Thoughts

If you are a person who has to fulfill most of your work with the help of a mechanical pencil, you should gain knowledge about it as much as possible. Also, it’s better to bring lead according to the size of the diameter of your mechanical pencil before asking questions like “can you put any size lead in a mechanical pencil”?

It’s simply because leads require the right of treatment, otherwise, they will not work properly no matter how thick or hard they are. Therefore, you better bring all types of lead sizes and mechanical pencils for them to try out separately.
