If you are constantly overencumbered in Fallout 4, the answer usually is not “stop looting.” The real problem is that most players do not actually know which carry weight upgrades are worth using, which ones stack well, and which ones sound better than they really are.
Some players assume power armor automatically solves the problem. Others throw points into Strength and hope for the best. But in reality, some of the biggest carry weight boosts in the game come from stacking perks, armor mods, and temporary buffs together rather than relying on one magic fix.
In this guide, I’m breaking down what actually increases carry weight in Fallout 4, from perks and armor mods to power armor upgrades, food, chems, and companions.
No glitches. No console commands. No nonsense. Just what actually works.

🎒 Why Carry Weight Matters More Than People Think
Carry weight affects more than just whether you can pick up one more minigun.
It influences:
- how long you can loot before heading home
- how efficient settlement supply runs feel
- how annoying exploration becomes
- how manageable Survival Mode is
In Survival Mode, this matters even more because your base carry weight is lower, so understanding the system properly becomes a much bigger deal.
🧮 How Carry Weight Actually Works in Fallout 4
Your carrying capacity in Fallout 4 is based on a very simple formula:
200 + 10 × Strength
That means every single point of Strength gives you:
+10 carry weight
This is the first major thing players need to understand.
A lot of carry weight bonuses in Fallout 4 are really just Strength boosts in disguise. Once you understand that, you can stop guessing.
For example:
- +1 Strength = +10 carry weight
- +2 Strength = +20 carry weight
- +3 Strength = +30 carry weight
That brings up the real question:
Which methods give the biggest carry weight boost for the least effort?
Let’s break it down.
💪 Strong Back: Good, But Not Always the Best
The first perk most players think of is Strong Back.
It requires Strength 6, and the early ranks are simple:
- Rank 1: +25 carry weight
- Rank 2: +50 carry weight total
After that, Strong Back stops being about raw carry capacity and starts being more about convenience.
- Rank 3: lets you run while overencumbered by spending AP
- Rank 4: lets you fast travel while overencumbered in normal mode
- Survival Mode: Rank 4 helps prevent overencumbrance injuries
- Far Harbor Rank 5: reduces the AP cost of running while overencumbered by 50%
What actually matters?
If all you care about is the number going up, the main value of Strong Back is in the first two ranks.
That means:
- +25
- then +50 total
After that, the perk is still useful, but it becomes a utility perk, not a bigger carry-weight perk.
That distinction matters.
🐕 Lone Wanderer Is One of the Best Carry Weight Perks in the Game
This is where things get more interesting.
If you are not traveling with a normal companion, Lone Wanderer is one of the strongest carry-weight perks in Fallout 4.
It only requires Charisma 3.
- Rank 1: +50 carry weight and reduced damage taken
- Rank 2: +100 carry weight total and reduced damage taken
That means for raw carry weight, Lone Wanderer actually beats Strong Back.
The important Dogmeat detail
A lot of players still get confused about this:
Dogmeat does not cancel Lone Wanderer.
So if you want the carry weight bonus and still want some companion support, Dogmeat is the exception.
That makes Lone Wanderer + Dogmeat one of the most efficient non-power-armor carry setups in the game.
Which is better early: Strong Back or Lone Wanderer?
It depends on your build, but if you can support Charisma 3 and you are happy traveling solo or with Dogmeat, Lone Wanderer gives the bigger immediate boost.
Strong Back is still valuable, but Lone Wanderer hits harder for pure carry weight.
🛡️ Deep Pocketed Armor Is One of the Best Permanent Upgrades
Armor mods are one of the most practical ways to fix carry weight without redesigning your whole build.
The big ones are:
- Pocketed
- Deep Pocketed
Pocketed
- Arms and legs: +5 carry weight
- Chest: +10 carry weight
Deep Pocketed
- Arms and legs: +10 carry weight
- Chest: +20 carry weight
That means a full armor setup with Deep Pocketed across multiple pieces can add a serious amount of carry weight.
Why this is so strong
The biggest advantage is that it is:
- permanent
- always on
- not tied to a timer
- not dependent on food or chems
If you are not in power armor all the time, Deep Pocketed is one of the cleanest and most reliable carry-weight upgrades in Fallout 4.
It is also a good reminder that the idea of “just wear power armor” is too simplistic. A properly modded normal armor setup can do a lot of work, especially when combined with Lone Wanderer or Strong Back.
👕 Strength Clothing Helps — But Don’t Overrate It
Clothing helps carry weight when it boosts Strength.
A great example is Army Fatigues, which give:
- +1 Strength
- while still allowing you to wear armor over them
That works out to:
+10 carry weight
That is definitely useful, especially in a stacked setup.
But it is also the perfect example of something players sometimes overestimate.
A Strength outfit is helpful, but it is still only giving +10 carry weight per point of Strength. So clothing works best as a supporting piece of the build, not as your main carry solution.
🤖 Power Armor Only Becomes a Carry Weight Monster When You Mod It Properly
A lot of player confusion comes from power armor.
Many people assume power armor is automatically the best carry-weight answer.
That is not completely wrong — but it is incomplete.
What the frame does
A power armor frame sets your Strength to 11.
That already gives you a strong carry-weight baseline.
But there is an important tradeoff:
When you enter power armor, you stop benefiting from the carry bonuses on your standard armor and clothing underneath. So if you were relying on Deep Pocketed armor or Strength clothing, those bonuses no longer help while you are inside the suit.
The real carry power comes from mods
The single most important carry-weight power armor mod is:
Calibrated Shocks
- +50 carry weight per leg
- +100 total with both legs modded
That is huge.
It is one of the biggest legitimate carry-weight boosts in the game.
Motion-Assist Servos
For the torso, Motion-Assist Servos add:
- +2 Strength
- which equals +20 carry weight
Strength-boosting paint
Some full paint bonuses, such as military-style Strength bonuses, can also add:
- +1 Strength
- which equals +10 carry weight
What this really means
The myth-busting answer is simple:
Power armor is not automatically amazing for carry weight. Modded power armor is.
If you are using power armor without carry-focused leg mods, you are leaving one of its best advantages on the table.
🍖 Food, Chems, and Alcohol: Best Temporary Carry Weight Boosts
Temporary buffs are perfect for:
- loot runs
- dungeon clears
- salvage trips
- getting home when you are already overloaded
Grilled Radstag
One of the best carry-weight foods in the game is:
Grilled Radstag
- +25 carry weight
This is especially strong because it boosts carry weight directly instead of indirectly through Strength.
Buffout
- +2 Strength
- effectively +20 carry weight
Bufftats
- +3 Strength
- effectively +30 carry weight
Whiskey
- +2 Strength
- effectively +20 carry weight
Of course, alcohol comes with other effects, so it is not always the cleanest option.
Party Boy / Party Girl synergy
If you have Party Boy / Party Girl Rank 2, alcohol effects are boosted.
That means drinks like whiskey can become much stronger, and crafted alcohol-based options can become surprisingly powerful for temporary carry builds.
Direct buffs vs Strength buffs
This is the distinction players should remember:
- Direct carry weight buffs like Grilled Radstag are easier to evaluate
- Strength buffs also work, but you have to convert them mentally into carry weight
Both work. But direct carry-weight buffs are usually simpler and more consistent.
🧍 Companions Help — But There’s a Tradeoff
Companions obviously help with inventory because they can carry gear for you.
And if you invest into Inspirational, companions can gain extra carry weight as well.
But here is the tradeoff:
If you bring a normal companion, you lose Lone Wanderer.
That means potentially giving up:
- +50 carry weight
- or +100 carry weight
depending on your rank.
So companions are not automatically the best carry-weight answer. In some builds, Lone Wanderer + Dogmeat is actually the stronger setup.
This is why the real question is not just:
“Can my companion carry junk?”
It is:
“Is this companion worth giving up one of the strongest carry perks in the game?”
✅ What Actually Works Best
If we rank the carry-weight methods by practical usefulness, here is the clean breakdown:
Best perk for solo players
Lone Wanderer
- huge return for low investment
- especially strong with Dogmeat
Best permanent armor solution
Deep Pocketed armor
- always on
- stacks across multiple pieces
- no timer or condition
Best power armor solution
Calibrated Shocks
- by far the biggest reason to use power armor for carry weight
Motion-Assist Servos
- a great secondary boost
Best temporary solutions
- Grilled Radstag
- Buffout
- Bufftats
Best overall approach
The best carry-weight builds in Fallout 4 do not rely on one fix.
They come from stacking multiple good methods together.
That is the real answer.
Final Thoughts
So no, power armor alone is not the answer.
No, dumping a few points into Strength is not the answer either.
And no, Strong Back is not the only perk that matters.
What actually works is understanding the numbers.
- Lone Wanderer is stronger than many players realise
- Deep Pocketed armor is more useful than it gets credit for
- Calibrated Shocks are one of the biggest carry-weight boosts in the game
- Grilled Radstag is an excellent emergency carry consumable
Once you understand how these systems stack, carry weight becomes much easier to manage.
