4mm Vs 5mm Arrows (Key Differences)




4mm and 5mm arrows are two different sizes of arrows used in archery. The main difference between them is their diameter. 4mm arrows have a smaller diameter than 5mm arrows, which makes them more accurate and less affected by wind drift or other external factors. However, 5mm arrows have larger fletchings, which can help stabilise the arrow in flight. So, a question arises: Which one is the best between 4mm Vs 5mm Arrows?

4mm Vs 5mm Arrows

There are many factors to consider when choosing between 4 mm arrows and 5 mm arrows. You must consider your bow type, archery style, and personal preference. To know the pros and cons and the perfect diameter, read below. Let’s dive into deep-

Key Differences

In short, if you think of better penetration and less wind drift, then you choose the 4 mm arrows. If you want larger fletching and less downrange velocity, then go for the 5 mm arrows.5mm arrows are also more affordable than 4 mm arrows. Give preference to your shooting style.

Key findings

4mm Vs 5mm Arrows

There are many differences between 4 mm arrows and 5 mm arrows. Some features of 4 mm arrows and 5 mm arrows are explained below:

4mm Vs 5mm Arrows

Wind Drift

The surface area of the arrow shaft is critical when it comes to wind drift. Wind drift is possibly versatile on your arrow shafts area as well as penetration. The axis arrows are very crucial in archery.Usually, the Eastern hunter faces less problem with wind drift. Consequently, the Western hunter may need help with wind velocity.


4 mm arrows have a comparatively smaller diameter than 5 mm arrows. Foam targets are suitable for both 4 mm and 5 mm arrows. As short as the arrow shaft diameter, it will face fewer drifts. If you want to reduce your wind drift, you can do it easily by decreasing the arrow diameters. Dip six 4 mm arrows offer better speed whereas deep six 5 mm arrows offer stability. 

One more thing to keep in mind is that Arrow length depends on the draw length. The optimal length is varied with 4 mm and 5 mm arrows. So, it is very crucial to match the arrow length with the draw length for optimum accuracy.

However, you can see that 4 mm arrows will help you quickly minimize the wind drift problem. Instead, in 5 arrows, you may be faced with wind drift.


Weight is an important consideration when selecting arrows. A smaller arrow weight can lead to a proper arrow flight. In this case, the weight is not considerable because both 4mm arrows and 5 mm arrows are relatively the same in weight. So,40-60  pounds of draw weight is recommended for 4 mm arrows.

Downrange Velocity

At the time of shooting, an arrow sometimes slows down when it flies. It is nothing but because of the velocity of downrange.

Friction is an important consideration when shooting an arrow. The average speed of the arrow may decrease because of friction from the air: the larger the diameter, the more friction faces.

4 mm arrows are comparatively smaller in diameter than 5 mm arrows. As a result, the surface area of the 4 mm arrow shaft is less. So, measure the arrow shaft length properly to get optimum accuracy for your specific bow. If the surface area of the arrow shaft is less, it may face less friction and slow down.

Remember that the bigger the area of the arrow, the more speed and power there is. The 4 mm helps to maintain the speed accurately, and it takes most of the initial weight. Easton axis arrows are also popular for providing improved accuracy.


Budget is the most important among the archers. Because you may need the available budget, the arrow, which is cost-effective, will be better for some archers.

Typically, the cost of deep  six 4mm arrows ranges from around $95 to $170. A bit less expensive option is packs of twelve.

On the opposite side, the 5mm arrows cost a range of around 80 -155 dollars per 6 arrows. It would cost you more if you go for single arrows. You may use Eatson’s insert tool for optimum performance.

However, above are the key differences between 4 mm arrows and 5 mm arrows. You may have a personal preference for choosing the one. Give priority to your comfort and shooting style.

Key Differences Between 4mm Vs 5mm Arrows

There are many differences between 4 mm vs 5 mm arrows. Here are some key differences described below:

FletchingSmaller fletching is present in the 4 mm arrows.Larger fletching is present in the 5 mm arrows.
Bow Compatibility4 mm arrows are suitable for certain bows.5 mm arrows are suitable for broader-range bows.
AccuracyThe 4 mm arrows are more precise.5 mm arrows are less affected by wind.
Budget4 mm arrows, per 6 arrows are available within( 90-170)$5mm arrows, per 6 arrows are available for 80$-155$.

Now, you know the critical differences between the 4 mm arrows and 5 mm arrows. You can also think about 4mm vs 5mm fmj arrows. A 4 mm fmj arrow typically offers more accuracy and speed, and a 5 mm fmj arrow provides more kinetic energy. It is better for large hunting games.

An ideal choice between the arrow depends on your personal preference, specific bow type, and archery style.

The Pros And Cons Of 4mm Arrow

There are many advantages of a 4 mm arrow, which depend on various factors. Here are some pros and cons of 4 mm arrows:
