Improving Your Aim in Call of Duty: Modern Warfare

Last updated:

Originally published for Call of Duty: Modern Warfare (2019). The thumbstick guidance in this article is evergreen and applies to FPS games broadly. Game-specific references reflect the original 2019 publication context. Current SCUF controller recommendations have been updated to reflect the live lineup.

When it comes to improving your game, while paddles a great difference, nothing improves your aim more than having the right thumbsticks.

Everyone has different hand sizes, thumb lengths, and preferences. That’s why SCUF thumbsticks are interchangeable: to match your unique preference of comfort and playstyle. 

Step One: Identify your Playstyle

Are you someone who likes to plan out a strategy and take their time to take out the enemy? Or do you prefer to take a more direct aggressive approach? Do you like shotguns or assault rifles more?

Whatever your preferred style, it’s a key part in what thumbsticks will suit you best. 

Step Two: Understanding Thumbstick Shape and Length

There are two parts to the thumbstick: its shape and its length. 

  • Concave Thumbsticks are designed for more movement control. 
  • Domed Thumbsticks are designed for more accuracy. 
  • Short Thumbsticks are designed for quicker movement speed.
  • Tall Thumbsticks are designed to have more angle to play with and more precise aiming. 

Step Three: Choosing Thumbsticks

For aggressive players, like SMG players, we recommend a short concave thumbstick on the left and a short domed thumbstick on the right. You’ll be quick to move and ready to quickly aim.

For defensive players, like rifle or sniper players, we recommend a short concave thumbstick on the left and a tall domed thumbstick on the right. You can still move quickly, but also be the most accurate when aiming. 

Try out different thumbstick types and combinations to find the ones that fit your playstyle, or change it up when you’re in the mood for something different.

How Thumbstick Height Affects Aim in FPS Games

Height Precision Speed to full deflection Learning curve Best for
Short Standard Fastest — less travel needed Low — feels like stock controller Aggressive play, SMG rushers, low-sensitivity players
Medium Balanced Moderate Low All-round players, transitioning from stock height
Tall Higher — more arc for fine adjustments Slower — more travel to full deflection Medium — may need sensitivity adjustment Defensive play, snipers, long-range rifles, high-sensitivity players

Do Thumbstick Extenders Improve Aim in FPS Games?

Thumbstick extenders — add-on caps that increase the effective height of a stock thumbstick — work on the same principle as a taller interchangeable stick: more physical height gives you a larger range of motion for the same in-game input, which can support finer micro-adjustments when aiming.

Whether extenders help depends on several factors:

  • Hand and thumb size: Players with larger hands and longer thumbs often find taller sticks more natural. Shorter thumbs may find very tall sticks harder to reach full deflection on comfortably.
  • Sensitivity settings: The benefit of a taller stick is most noticeable at medium-to-high sensitivity. At very low sensitivity the additional arc matters less.
  • Playstyle: Defensive, long-range, or sniper-focused players benefit most. Aggressive rushers who snap between targets quickly may prefer shorter sticks.
  • Practice: Any height change requires an adjustment period. Switching to a taller stick and immediately judging it worse is normal — give it several sessions before concluding.

SCUF interchangeable thumbsticks offer the same functional benefit as extenders but with a more secure fit, consistent feel, and shape options (concave or domed) that third-party extenders typically do not provide. They are included with current SCUF controllers and available separately for compatible models.

Custom Controller Upgrades for FPS Gaming

Thumbsticks are one part of a broader set of controller upgrades that benefit FPS players. Here is an overview of the key upgrades available on current SCUF controllers across Xbox/PC and PS5, and what each adds for competitive play:

Upgrade What it does for FPS play Available on
Interchangeable thumbsticks Match height and shape to playstyle; no tools needed All current SCUF controllers
Rear paddles Jump, reload, crouch, or sprint without lifting thumb from aim stick All current SCUF controllers
Adjustable Instant Triggers Shorter trigger travel for faster fire — toggle between instant and full pull Omega (PS5), Valor Pro Wired/Wireless (Xbox/PC)
Anti-drift thumbstick tech Hall Effect or TMR sensors reduce stick drift over time All current SCUF controllers
Performance grip Textured surface reduces slippage during long sessions All current SCUF controllers
Interchangeable faceplate Cosmetic; also allows platform-specific button customization on some models All current SCUF controllers
On-board remapping / profiles Save up to 3 layout profiles; switch per-game without software All current SCUF controllers

Frequently Asked Questions

Do thumbstick extenders or taller sticks improve aim?


They can, for some players in some setups. A taller stick increases the physical range of motion for the same in-game input, which allows finer micro-adjustments when aiming. The benefit is most noticeable at medium-to-high sensitivity settings and for defensive/long-range playstyles. Results depend on hand size, thumb length, sensitivity, and how long you practice with the new height before judging it. There is no single "best" height — it is a personal fit.



Are taller thumbsticks better for aiming?


For precision aiming — particularly in sniper or long-range rifle roles — taller sticks offer more leverage and finer control over small movements. For aggressive, fast-snap play, shorter sticks are typically more comfortable because they reach full deflection with less thumb travel. Most FPS players use a short concave on the left (movement) and a taller domed on the right (aim), but this is a starting point rather than a universal rule.



What is the best thumbstick height for FPS games?


There is no single best height. A common starting setup for FPS games is short concave (left) and short or tall domed (right), depending on whether you play aggressively or defensively. Start with the setup closest to what you already play and make one change at a time, giving yourself several sessions to adjust before evaluating.



Do FPS thumbsticks (domed sticks) actually work?


Yes, for players who do fine aim work with the tip of their thumb rather than the pad. Domed sticks allow the thumb to slide smoothly for small directional corrections, which suits precision aim. Concave sticks grip the thumb pad securely, which suits directional movement where you want resistance. Using the right shape for each stick — concave for movement, domed for aim — is a common and well-supported starting recommendation.



Is a custom Xbox controller worth it for competitive FPS gaming?


For most competitive FPS players, rear paddles are the single most impactful upgrade — being able to jump, reload, or crouch without removing your thumb from the aim stick is a consistent, practical advantage. Adjustable instant triggers, performance grip, and interchangeable thumbsticks add further marginal benefits. Whether the combined cost is worth it depends on how seriously and frequently you play. The SCUF Valor Pro is the current Xbox/PC option from SCUF that includes all of these features.



How do I improve aim in FPS games generally?


Controller hardware is one factor among many. The most impactful changes for most players are: tuning in-game sensitivity (start lower than feels natural, build up gradually), enabling aim assist at a level that suits your playstyle, practising target switching in aim-training modes, and reducing physical fatigue through better grip and ergonomics. Thumbstick choice can support these gains but does not replace the fundamentals of practice and settings tuning.



What controllers do competitive gamers use?


Competitive FPS players across consoles and PC commonly use controllers with rear paddles and short-travel triggers. SCUF controllers have been used at various high-level competitive events. On Xbox/PC, the current SCUF option is the Valor Pro; on PS5, it is the SCUF Omega.
