方塊是占據世界空間的基本結構單位。

碰撞箱是一個玩家無法穿過的固體空間，由一個或多個坐標軸方向上的長方體，即邊界箱組成。實體同樣擁有各自的邊界箱，但處理方法與固體空間不同（除了船）。

不要與判定箱相混淆，判定箱指的是玩家可以互動的區域（攻擊，挖掘，右鍵等）。

同樣不要與模型相混淆，模型只是方塊或實體在屏幕上顯示的圖形。
最後，一些方塊擁有各自的「效果箱」，如液體，梯子，仙人掌，壓力板等。它們擁有特殊的代碼與應用。

例如：按鈕沒有碰撞箱，因此玩家可以從中穿過。但它擁有可以被玩家點擊的判定箱。

又例如：屏障方塊擁有完全相同的邊界箱與判定箱，但是在代碼中被強制編寫為不顯示模型。

本頁面列出了 1.8 版本中所有方塊的碰撞箱與屬性。

擁有特殊屬性或沒有碰撞箱的方塊則提及於各自的頁面。

Simple Collision Boxes

這些碰撞箱由單個邊界箱組成。方塊按長度，寬度，再到高度的順序排列。

方塊	寬度（b）	高度（b）	信息
石牆（4 面連接）	1 × 1	1.5	相鄰的方塊必須是固體方塊，石牆或柵欄門。
普通方塊	1 × 1	1
靈魂沙	1 × 1	0.875	看上去像完整方塊，但實際上矮 2 個像素。減緩其上方實體的行走速度。
末地傳送門框架	1 × 1	0.8125
附魔台	1 × 1	0.75
床方塊	1 × 1	0.5625	底部看上去是空的，但實際有碰撞箱。
台階	1 × 1	0.5	可上下翻轉。
陽光傳感器	1 × 1	0.375
活板門（水平放置）	1 × 1	0.1875	可上下翻轉。可以翻轉到豎直方向。
紅石中繼器	1 × 1	0.125
地毯	1 × 1	0.0625
睡蓮	1 × 1	0.015625	僅有 ¼ 個像素高。
雪	1 × 1	0 0.125 0.25 0.375 0.5 0.625 0.75 0.875	雪看上去比實際高度高 2 個像素。一層的雪雖然沒有高度，但仍然有模型。
石牆（3 面連接）	1 × 0.75	1.5	可改變朝向（4 種變體）。相鄰的方塊必須是固體方塊，石牆或柵欄門。
鐵砧	1 × 0.75	1	碰撞箱居中。可改變朝向（2 種變體）。看上去比實際要窄。
活塞底座（激活狀態）	1 × 0.75	1	可改變朝向（4 種變體）。
石牆（相對 2 面連接）	1 × 0.375	1.5	碰撞箱居中。可改變朝向（2 種變體）。相鄰的方塊必須是固體方塊，石牆或柵欄門。在上方放置方塊會改變它的外觀，但碰撞箱不變。 despite its appearance being different.
Fence (2-opposite)	1 × 0.25	1.5	Centered. Orientable (2 variants). Adjacent blocks must be solid, fences, or fencegates.
Fencegate	1 × 0.25	1.5	Centered. Orientable (2 variants). Can be flipped to a variant with no collision box.
Trapdoor (vertical)	1 × 0.1875	1	Orientable, Inversible (8 variants). Can be flipped to its horizontal variant.
Door	1 × 0.1875	1	Orientable (4 variants). Can be flipped to another variant.
Ladder	1 × 0.125	1	Orientable (4 variants). Can be climbed by entities.
Pane (2-opposite)	1 × 0.125	1	Centered. Orientable (2 variants). Adjacent blocks must be solid, or panes/bars.
Chest (long)	0.9375 × 0.875	0.875	Must be next to another chest.
Dragon Egg	0.875 × 0.875	1	Centered. Looks drastically different from its collision box.
Cactus	0.875 × 0.875	0.9375	Centered. Hurts entities close to it.
Chest	0.875 × 0.875	0.875	Centered.
Cake	0.875 × 0.875 0.875 × 0.75 0.875 × 0.625 0.875 × 0.5 0.875 × 0.375 0.875 × 0.25 0.875 × 0.125	0.5	The full cake is centered. Each bite takes away 0.125b from the West (-X)
Wall (2-adjacent)	0.75 × 0.75	1.5	Orientable (4 variants). Adjacent blocks must be solid, walls, or fencegates.
Wall (1-sided)	0.75 × 0.5	1.5	Orientable (4 variants). Adjacent block must be solid, a wall, or a fencegate.
Fence (1-sided)	0.625 × 0.25	1.5	Orientable (4 variants). Adjacent block must be solid, a fences, or a fencegate.
Wall (default)	0.5 × 0.5	1.5	Centered.
Cocoa (big)	0.5 × 0.5	Low: 0.1875 Top: 0.75	Orientable (4 variants). 1 pixel away from the wall it's attached to. Trivia: the top texture is only 7 pixels wide.
Head (walled)	0.5 × 0.5	Low: 0.25 Top: 0.75	Orientable (4 variants).
Head (default)	0.5 × 0.5	0.5	Centered. A head can be placed diagonally (16 variants total), but the collision box doesn't change.
Pane (1-sided)	0.5 × 0.125	1	Orientable (4 variants). Appears 1 pixel longer than it really is. Adjacent block must be solid, or a pane/bar.
Cocoa (medium)	0.375 × 0.375	Low: 0.3125 Top: 0.75	Orientable (4 variants). 1 pixel away from the wall it's attached to.
Flowerpot	0.375 × 0.375	0.375	Centered.
Fence (default)	0.25 × 0.25	1.5	Centered.
Cocoa (small)	0.25 × 0.25	Low: 0.4375 Top: 0.75	Orientable (4 variants). 1 pixel away from the wall it's attached to.

Composite Collision Boxes

Collision boxes that consist of two or more bounding boxes.

"~~Except~~" represents an intangible zone rather than a tangible one (simpler to describe that listing all bounding boxes)

Block	Widths (b)	Height (b)	Comments
Stair (normal)	Base: 1 × 1 Top: 1 × 0.5	Base: 0.5 Top: 1	Orientable, Inversible (8 variants).
Stair (outer)	Base: 1 × 1 Top: 0.5 × 0.5	Base: 0.5 Top: 1	Orientable, Inversible (8 variants). Depends on adjacent stair blocks.
Stair (inner)	Base: 1 × 1 ~~Except:~~ -0.5 × -0.5	Base: 1 ~~Except:~~ -0.5	Orientable, Inversible (8 variants). Depends on adjacent stair blocks.
End Portal Frame (eye)	Base: 1 × 1 Eye: 0.375 × 0.375	Base: 0.8125 Eye: 1	The eye looks bigger than it is. (Appears 8 px in width, but is actually 6 px wide)
Hopper	Base: 1 × 1 ~~Except:~~ -0.75 × -0.75	Base: 1 ~~Except:~~ -0.375	The bottom doesn't look tangible, but it actually is. The interior floor is 1 pixel lower than it looks.
Cauldron	Base: 1 × 1 ~~Except:~~ -0.75 × -0.75	Base: 1 ~~Except:~~ -0.6875	The bottom doesn't look tangible, but it actually is. The interior floor is 1 pixel higher than it looks
Brewing Stand	Base: 1 × 1 Rod: 0.125 × 0.125	Base: 0.125 Rod: 0.875	The base looks very different from its bounding box.
Piston Head (Vertical)	Head: 1 × 1 Arm: 0.25 × 0.25	Head: 0.25 Top: 1	Centered. Inversible. The arm is shorter than it looks (model extended by 4px).
Piston Head (N/S/E)	Head: 1 × 0.25 Arm: 0.75 × 0.5	Head: 1 Arm-Low: 0.375 Arm-Top: 0.625	Orientable (3 variants). Accurate model. The arm is wider than it looks (0.5m width). The arm is shorter than it looks (model extended by 4px).
Piston Head (West)	Head: 1 × 0.25 Arm: 0.75 × 0.25	Head: 1 Arm-Low: 0.25 Arm-Top: 0.75	Bugged (fixed in 1.9). Accurate model. The player can walk through a west extended piston. In 1.9, piston heads were changed to match their model.
Fence (4-sided)	Post: 0.25 × 0.25 Sides: 0.375 × 0.25	1.5	Adjacent blocks must be solid, fences, or fencegates.
Fence (3-sided)	Post: 0.25 × 0.25 Sides: 0.375 × 0.25	1.5	Orientable (4 variants). Adjacent blocks must be solid, fences, or fencegates.
Fence (2-adjacent)	Post: 0.25 × 0.25 Sides: 0.375 × 0.25	1.5	Orientable (4 variants). Adjacent blocks must be solid, fences, or fencegates.
Pane (Default / 4-sided)	Sides: 0.5 × 0.125	1	Adjacent blocks must be solid, or panes/bars.
Pane (3-sided)	Sides: 0.5 × 0.125	1	Orientable (4 variants). Adjacent blocks must be solid, or panes/bars.
Pane (2-adjacent)	Sides: 0.5 × 0.125	1	Orientable (4 variants). Adjacent blocks must be solid, or panes/bars. The exterior corner has a 1px wide opening (despite the model showing a clean 90° corner).
