How hard is it to decide the right nail sizes for framing if you don’t know anything about it?

I am sure; you want to use the right nail for your nail gun to accomplish a particular task.

To do so, knowing the different size nails is truly important as well as the types and their best use.

I have left no stone unturned to help you out exactly on that.

That means in this article; I am going to give you proper knowledge on framing size nails, their types, and applications for your framing projects.

So, without any further delay, let’s get down to it. Shall we?

Nail Sizes for Framing: What Size Nails Do We Need for Framing

What Size Nails Do You Need For Framing?

Who doesn’t know that framing nails vary in length?

I bet you know that.

But do you know how we people denote the different lengths?

Hang on with me if you don’t know that yet.

Based on the differences in length, diameter, gauge, we designate the common nails for framing in different names. All of them are symbolized by “d” (more on this later).

So, what are those different denotations of framing nails?

Here you go – 2d, 3d, 4d, 5d, 6d, 7d, 8d, 10d, 12d, 16d, 20d, 30d, 40d, 50d, 60d, 70d, 80d, etc.

Now, what the heck is the “d” here? And what is the length of each of these?

“d” is nothing but the symbol for a penny. “d” stands for a denarius, which is a Roman coin similar to the penny. It is believed that 2d needs 2 English pennies to buy 100 nails for framing, that’s why it is designated as 2d.

In America, the retailers use the penny system instead of length to identify framing nails.

As I said, they vary in length and other parameters like diameter and gauge. However, not all sizes are commonly used in framing.

16d, 10d, 8d, 6d are the common nails are used in framing.

Keep in mind; these common nails for framing are categorized mainly into four types – common, box, cooler, and sinker.

Common size nails for framing have the most substantial diameter shank than others. The heavy shank allows a common nail to carry the heavy structural load.

On the other hand, the box nails have smaller diameter shank hence it’s lighter. They are mainly designed to reduce splitting when you assemble wooden boxes.

Both the cooler and sinker nails have a vinyl coating that helps them to go through the wood smoothly.

The sinker nails have a textured head that prevents hammers from sliding.

Let’s dig a little deeper!

Now I am going to give you some ideas about the most commonly used nail sizes for framing (i.e. 16d, 10d, 8d, 6d).

16d Nail Lengths/16d Nail Size

16d Nail Length/Nail Size

So, first of all – what are 16d nails, and what are the types of 16d nails?

I believe you got the answer already if you read the above point that I wrote on ‘framing nailer length and variation.’

That being said, I haven’t told you about the exact length, diameter, and gauge of 16d nails.

Not to mention, I am going to list down the measurement for both common size nails for framing and box nails.

So, how big are the 16 penny nails? What is the diameter? And What gauge are the 16 penny nails?

Here is the answer (two types of 16d nails):

Common 16d nails –

  • Length: 3.5 inches.
  • Diameter: Diameter of 0.162 inches
  • Gauge: 8

Box 16d nails –

  • Length: 3.5 inches.
  • Diameter of the nail: 0.135 inches.
  • Gauge: 10

16d nails are the most commonly found nails (diameter of 0.162 inches). These nails are the best for construction-related works mostly.

Our Best Choice:

10d Nail Length/Nail Diameter/10d Nail Size

10d Nail Lenght/Nail Diameter/Nail Size

Like the 16d framing nails that I discussed earlier, I will be answering the following significant questions for 10d nails too.

How long are the 10d nails? What is the diameter of the 10d nails? And what gauge is a 10 penny nail?

Of course, I will be answering the measurement for both common and box nails.

For common 10d nails –

  • Length: 3 inches.
  • Diameter of the nail: 0.148 inches.
  • Gauge: 9

And for box 10d nails –

  • Length: 3 inches.
  • Diameter: 0.128 inches.
  • Gauge: 10.5

10d nails are perfect for making door trimmers, attaching flat board faces.

You guessed it right.

Let’s get busy with finding the answer to the same questions for 8d framing nails.

  • Length: 2.5 inches.
  • Diameter: 0.131 inches.
  • Gauge: 10.25

And for box 8d nails –

  • Length: 2.5 inches.
  • Diameter: 0.113 inches.
  • Gauge: 11.5

You should use 8d nails where a longer nail is not required. To be specific, 8d nails are perfect for attaching subfloors, toenailing, furring strips, sheathing.

6d nails are perfect for small interior jobs, joining flat woods, etc. where you don’t need large nails.

Now let’s get the answers to the same old questions. I mean the different measurements of 6d nails.

For common 6d nails –

  • Length: 2 inches.
  • Diameter: 0.113 inches.
  • Gauge: 11.5

Metal Anchors

Metal Anchors

Well, these are not the best nails that I’ve talked about so far in this article.

These are called metal anchors.

First thing first. What is a metal anchor? And what does it do?

Metal anchors are used as wall anchors. Their primary task of these anchors is to ensure the support to the wall that is required for the wall to bear any load.

The anchor type certainly depends on the wall material, how it will be installed or removed, and last but not least, the weight of the load that will be hung.

Frequently Asked Questions

Question #1. What are the nail sizes for framing with a nail gun?

Answer: Here is the point. Not all framing nails will fit inside your framing nail guns magazine. So, when you buy the nail for your nail gun, make sure to check the compatibility issue first.

On top of that, different nail gun shoots different nails of varying lengths. For instance, typically a brad nailer shoots nail that has a length between 0.375 inches to 1.25 inches.

Ideally, you will have to select the perfect nail first based on your project, then pick the framing nailer that can shoot that particular nail.
