What Is Scope Magnification?

Scope magnification defines the ability of an optical device, such as a telescope, binoculars or a rifle scope, to make an object appear larger or closer. This feature makes distant targets clearer and allows for more precise shots.

Scope magnification is typically expressed as a ratio and consists of a number followed by the symbol "x " — for example, 3x, 4x or 6x.

Fixed vs. Variable Scope Magnification

Scope magnification can be divided into two main types: fixed magnification and variable magnification.

Fixed magnification offers a single level of magnification. For example, a 4x magnification means that the image seen through the scope appears four times larger than it does with a naked eye.

Variable magnification offers adjustment of the magnification level within a specified range. For example, if a scope is labeled 3-9x, this means the magnification levels can be changed from 3 to 9 times.

Fixed Magnification Scopes vs. Variable Magnification Scopes

Depending on the magnification flexibility, outdoor enthusiasts can choose between fixed and variable magnification scopes.

Fixed magnification scopes are set at a specific power and do not allow you to adjust the magnification level.

Praised for their simplicity, reliability and durability, fixed magnification scopes are a good option in scenarios where a consistent magnification level can be used — for example in certain types of hunting or competition shooting scenarios.

Variable magnification scopes, also known as zoom scopes, have a more complex design compared to fixed magnification scopes. They often include additional features, such as parallax adjustment and illuminated reticles.

Variable magnification scopes allow you to adapt to different shooting scenarios where target distances can vary. For example, you can use them in tactical and long-range precision shooting, where it’s crucial to be able to zoom in for precise shots at a distance.

What Do The Numbers On A Scope Mean?

The numbers on a rifle scope provide information about the magnification strength and the size of the objective lens. The numbers are typically a part of the scope name.

The first set of numbers before the “x” shows the magnification power and indicates whether the scope offers fixed (4x, for example) or adjustable magnification (4-12x).

The value following the "x" is the diameter of the objective lens, measured in millimeters (mm). The size of the objective lens determines how much light can enter the scope and directly affects brightness and clarity.

A larger objective lens allows more light, potentially providing a brighter image — especially in low-light conditions.

Here are several examples of how an objective lens affects performance:

• Scopes with small objective lens like 24mm produce a limited light gathering effect and can be used in well-lit conditions.
• Scopes with a large objective lens like 56mm gather a significant quantity of light and produce a brighter image with better visibility — they are a great option for low-light conditions, such as dawn or dusk.
• Scopes with an extra-large objective lens like 72mm provide maximum light transmission — which is why they are recommended for extremely low-light conditions.

In some cases, you might have additional numbers on your scope that denote tube diameter. These numbers refer to the size of the main body of the scope, where the lenses and reticle are housed.

The most common tube diameters are 1 inch and 30mm. The larger diameter can offer more room for internal adjustments and potentially better light transmission.

How To Choose The Right Scope Magnification

From determining your intended use to considering environmental conditions, the right scope for your rifle depends on several factors.

To choose a scope magnification:

• Identify your shooting purpose: Determine what you’ll use the scope for, whether hunting, long-range precision shooting or tactical applications. For hunting in dense terrain, consider a scope with low to moderate magnification, such as 3-9x. For precision shooting at longer ranges, opt for a higher magnification scope, like 6-24x or 8-32x, for accurate target placement. For close-quarters engagements in tactical scenarios, choose a low magnification scope like 1-4x.
• Choose between variable vs. fixed magnification: Decide between a fixed magnification scope, which offers simplicity, or a variable magnification scope, which provides adaptability to various distances. For shooting at a fixed distance, select a fixed magnification scope, like 10x. For hunting in diverse settings, opt for a variable magnification scope, like 2-10x.
• Assess the target size: Consider the size of your targets to match the magnification power and achieve optimal shot placement. For hunting large game, use a moderate magnification like 4-12x, which provides a balance between target visibility and field of view. For precision shooting with small targets, consider higher magnification scopes like 10-40x to see every detail clearly.
• Consider the field of view: Find a compromise between magnification and field of view, keeping in mind that higher magnification often narrows the field. For tactical situations with quick target acquisition, opt for a low to mid-range magnification scope, such as 1-6x, to maintain a wide field of view. For precision shooting at longer distances, choose scopes with higher magnification like 5-25x, which will allow you to focus on distant targets.
• Consider environmental conditions: Consider how lighting, weather and other factors may affect magnification in different shooting scenarios. For low-light conditions, choose a scope with a larger objective lens like 50mm to maximize light transmission. For hunting in various environments, choose a versatile scope like 3-9x.
• Test and adjust: If possible, test different magnification levels in real shooting scenarios and adjust based on your personal preferences, comfort and performance.

FAQS About Scope Magnification

Still have unanswered questions? Check out some frequently asked questions about scope magnification in the section below.

How does rifle scope magnification affect the field of view?

Higher magnification typically narrows the field of view, making it important to balance magnification with the need for a broader view — especially in dynamic shooting situations.

Is higher magnification always better?

Not necessarily. The magnification that will be best for you depends on your shooting application. For example, too much magnification in close-quarters scenarios can be impractical, while insufficient magnification for long-range shots can decrease accuracy.

Can I use the same scope magnification for different types of shooting?

In some cases, It is possible to use the same scope magnification for different types of shooting, but the effectiveness will largely depend on the magnification level. For example, you can use a moderate fixed magnification, like 4x, for both close-quarters and medium-range shooting.

Can I use a high-magnification scope to hunt moving targets?

To hunt moving targets, opt for lower magnification scopes, which offer a wider field of view.

What magnification scope should I choose for shooting from a moving platform, such as a boat or a vehicle?

For shooting from a moving platform, opt for lower magnification scopes like 1-4x. This will allow you to stay aware of your surroundings and track the target easily.

Can I use a scope with high magnification for hunting in dense woods?

Using a scope with high magnification in dense woods might not be ideal. Choose a scope with a low to moderate magnification, which provides a wider field of view and allows you to see targets in close quarters.

How does magnification affect field of view?

Field of view decreases as magnification increases. For optimal shooting performance, use enough magnification for your needs without sacrificing a wide field of view.

Does weather affect scope magnification performance?

Adverse weather conditions like fog, rain and snow can impact visibility. If you are planning to shoot in extreme conditions, opt for scopes with weather-resistant features and a special lens coating.
