Minecraft Stack Calculator

Welcome to the Minecraft stack calculator! Whether you're just building a circle in Minecraft or a constructing a huge Nether portal, you're bound to work with more than 64 items at some point. Here, we'll show you how to calculate Minecraft stacks for a given number of items and how you can apply simple mathematics to solve the problem. We'll also teach you some handy in-game stack-related tricks, such as how to drop and how to split a stack in Minecraft.

In everyone's favorite blocky sandbox game, the player's inventory has slots in which you can place items. Minecraft generally allows you to place up to 64 items of the same type into one slot. This pile of items is called a stack.

Note that we said "generally". While blocks and most items in the game stack up to 64 in one slot, there are a few exceptions. Some items only stack up to 16 in one slot; these include snowballs, eggs, and Ender Pearls (a vital ingredient for finding the End Portal). Tools and armor (or anything with in-game durability) do not stack at all, limiting the player to one item per slot.

You can easily apply the items stacking concept for your daily usage with our Minecraft stack calculator:

1. Decide which way you're calculating. Are you converting stacks to items or vice versa? Select the appropriate option at the top of the Minecraft stack calculator.

2. If you're converting to stacks, tell the calculator how many items you have and the maximum stack size. It will determine how many stacks and how many leftover items you have.

3. If you're converting to items, tell the calculator how many stacks and how many leftover items you have. It will determine how many items in total you have.

Stacks help you manage your inventory. It compacts similar items into one slot, freeing them up so that other items can fill them. It makes moving items easier — you can pick up an entire stack of items at a time and move them to or from your hotbar, your inventory, or your chests. There are also some neat in-game shortcuts for manipulating stacks, which we'll discuss below.

Whether you want to get rid of excess cobblestone on your mining trip ⛏, or you want to throw your diamonds 💎 into your hopper-powered sorting system, it's helpful to know how to drop a stack of items in your Minecraft world. It's really simple:

1. Left-click once on the stack in your Minecraft player's inventory.

2. Move your cursor outside the inventory's interface so that it hovers over the world in the background.

3. Left-click again. This will drop the stack of items into the Minecraft world in front of you.

Occasionally, you don't need an entire stack. In these scenarios, it would be great to know how to split a stack of Minecraft items. In your inventory, right-click a stack. Half will remain in your inventory and the other half will be dragged by your cursor, ready to be placed somewhere else. So, when you want to give only half of your carrots 🥕 to the villager in exchange for emeralds, right-click the carrot stack and move it to the villager's trading slot. The other half will be safe in your inventory.

We've hopefully convinced you of the importance of item stacks. But how do we determine how many stacks an arbitrary number of items will fill up? And how many items will remain in a semi-full stack? We can calculate these with some quick formulas.

First, determine whether the item's maximum stack size is 64 or 16. Most items stack to 64, but some only stack to 16.

Then, knowing the total number of items we have, continue with these two formulas:

• The number of full stacks (that is, the number of slots that will contain the maximum number of items) can be determined with stacks = floor(total items / maximum stack size). The floor operation means to round down to the nearest integer.

• The number of leftover items can be calculated with leftover items = total items % maximum stack size. Here, % is the modulo operator — it means we use the remainder of the division between total items and maximum stack size.

We can also use these formulas backward. If we know how many stacks and leftover items we have, we can easily determine how many items we have in total with:

total items = stacks × maximum stack size + leftover items.

Suppose we've designed a small automatic wheat farm that delivers a harvest of 250 wheat 🍞 items every hour. We need to devise a storage strategy, but we can't until we know how many stacks of wheat we'll be handling. Let's put what we've learned into practice.

In Minecraft, wheat stacks to 64. Knowing the maximum stack size to be 64, we can calculate that 250 wheat translates to:

floor(250/64) = floor(3.906) = 3 stacks

…and an additional semi-full stack of:

250 % 64 = 58

Our wheat farm would, therefore, produce 3 stacks and 58 units of wheat every hour.

Suppose the wheat farm runs for 10 hours and delivers the promised 2,500 wheat. That would mean our farm produced:

floor(2,500/64) = floor(39.06) = 39 stacks

…and a semi-full stack of:

2,500 % 64 = 4

To store all this wheat, we'd need 40 slots of inventory space — that means we'd need at least one double chest.

Lastly, let's suppose we're building a tower, and our online schematics tell us we'll need 5 stacks plus 32 pieces of cobblestone. How many pieces of cobblestone is that in total? We can easily use the backward equations: 5 stacks and 32 pieces of cobblestone translates to:

5 × 64 + 32 = 352 pieces of cobblestone.
