About StackIT
From ThunderstoreServer-synced stack, weight and pickup control for Valheim. Tune stacks per resource (wood 3x, metal 2x), cut item weights by a percentage, raise carry capacity, and hold Shift to harvest a whole berry patch
📦 StackIT

Carry more of it, carry it further, and take the whole patch at once.
StackIT is a small, server-authoritative mod that decides two numbers for every item in the game: how many fit in a slot, and what one of them weighs. Both are multipliers you set once and forget — or, if you want the control, tune per category, per resource and per individual item, with exclusions and a hard ceiling. The server owns the settings and clients sync to it, so nobody has to compare config files.
It also stops you pressing E forty times in a berry patch: hold Shift and the whole patch comes up at once.
It deliberately never makes weapons, armour or tools stackable. Here is why.
📜 Contents
⚠️ Upgrading to 0.3
> Nothing changes on its own. Every new setting ships switched off: the four resource multipliers in > 3 - Stack Resources are 0 (follow the category, then the global multiplier), Stack Multiplier > Overrides is empty and Weight Reduction Bonus (%) is 0. A server that upgrades and touches nothing > computes exactly the stack sizes and weights it did on 0.2.3. > > Everyone needs 0.3.0. The new settings are server-synced and change what the server computes, so > clients on an older StackIT are asked to update rather than play with different numbers.
⚠️ Upgrading to 0.2
> Harvest All is on by default, and the key is Shift. Shift is also the run key, so sprinting up > to a berry bush and pressing Use while still holding it will take the whole patch, not one bush. > That is usually what you wanted anyway, but it is worth knowing before it surprises you. Change the > key or set Harvest All = false in section 7 - Pickup. > > Nothing else changes on its own. Auto Pickup Range ships at 2, which is exactly vanilla — > raise it yourself if you want harvests to collect themselves. > > Everyone needs the same version. The pickup settings are server-synced, so clients on an older > StackIT are asked to update rather than play without them.
⚠️ Upgrading from 0.0.1
> Weight reduction is on by default. 0.1.1 adds a Weight Multiplier that ships at 0.5, so > every item weighs half what it used to the moment you launch. That is a real balance change on an > existing server, and it is deliberate — bigger stacks are only worth having if you can carry them. > If you want the old behaviour, set Weight Multiplier = 1.0 in section 4 - Weight. > > Your stack multiplier carries over. It stayed in section 2 - Settings under the same key > precisely so your existing value survives the upgrade untouched. > > Everyone needs 0.1.1. Clients still on 0.0.1 will be asked to update, because they would compute > different stack sizes to the server.
⚔️ Features
📦 Bigger Stacks
One multiplier applied to the base stack size of every item that already stacks in vanilla. Defaults to 3x: 50 wood becomes 150, 20 trophies become 60. A Max Stack Size ceiling (default 9999) is applied afterwards, so a big multiplier on an already-big stack can never produce a silly number.
Stack sizes are always recomputed from the vanilla value, never from the current one. Turn the multiplier down mid-session and it genuinely goes down; push a new config from the server ten times and you get the same answer ten times.
🪶 Lighter Items
The other half of the problem. A multiplier on every item's weight, defaulting to 0.5 — half of vanilla. Two details matter:
- Items that weigh nothing in vanilla stay weightless. They are meant to be free.
- Everything else gets a Minimum Item Weight floor (default 0.01) so nothing rounds down to free
by accident.
On top of the multiplier there is a Weight Reduction Bonus (%): a further percentage taken off every item. Set it to 25 and everything is 25% lighter than the multiplier alone would make it — at the default multiplier of 0.5, a log that weighs 2 in vanilla ends up at 0.75. It ships at 0. Categories that have a multiplier of their own replace the global one, but the bonus is never replaced, so it is the one dial that moves every weight in the game at once. Weight Overrides and Excluded Items name an exact weight and are exempt; the minimum-weight floor still holds, so 100 leaves everything at the floor rather than at nothing.
🎒 More Carry Weight
Extra Carry Weight is a flat allowance added on top of vanilla's 300 and anything Megingjord is already giving you. It hooks the same call the encumbrance check and the inventory readout use, so the number in the corner of your inventory and the point at which you start waddling always agree. Defaults to 0 — the stack and weight multipliers usually get you there on their own.
