All about Inverted LEGO® Slopes: Indispensable building blocks for creative constructions
25 geassemánnu 2025
If you have ever turned over a LEGO® structure or looked at the underside of a roof structure, chances are you have come across an Inverted Slope. These special bricks are the counterparts of the standard sloped LEGO® bricks and offer unique possibilities for designers and builders. In this article, we dive deeper into the world of Inverted LEGO® Slopes: what they are, what variations there are, and how they are used in LEGO® creations.
What is an Inverted LEGO® Slope?
An Inverted Slope (also known as an "inverted slope or inverted roof tile") is a LEGO® part that slopes down instead of up. Unlike the standard slope often used for roofs and smooth finishes, an inverted slope is mainly used on the underside of structures or to create specific shapes, such as the inside of wings, vehicles, futuristic buildings or machines. These bricks are widely used in Advanced LEGO® MOCs (My Own Creations) and are popular with experienced builders because of their versatility.
The main types of Inverted Slopes
There are several types and sizes of the Inverted Slope, each with its own application. Below is an overview of the most popular varieties:
1. Inverted Slope 2x1 (Part 3665) Size: 2 studs wide, 1 stud deep, 1 brick high Angle: 45 degrees Characteristic: The simplest and most commonly used variant Use: Small finishes, vehicle details, angular structures
2. Inverted Slope 2x2 (Part 3660) Size: 2 studs wide, 2 studs deep, 1 brick high Angle: 45 degrees Feature: Square base, convenient padding for larger structures Use: Undersides of vehicles, houses, spaceships
3. Inverted Slope 33 3x1 (Part 4287) Size: 3 studs wide,1 stud deep, 1 brick high Angle: 33 degrees Characteristic: For less sloped structures Use: Slow, elegant slope at the bottom of a model
4. Inverted Slope 75 2x1x3 (Part 2449) Size: 2 studs wide, 1 stud deep, 3 bricks high Angle: 75 degrees Characteristic: High slowly rising LEGO® brick Use: Slow, elegant slope for e.g. rockeries
5. Inverted Slope Curved 2x1 (Part 24201) Size: 2 studs wide, 1 stud deep, 2/3 brick high Feature: Curved instead of straight Use: Flowing lines in spaceships or organic structures
6. Inverted Slope Curved 2x2 (Part 32803) Size: 2 studs wide, 2 studs deep, 2/3 brick high Feature: Curved instead of straight Use: Flowing lines in spaceships or organic structures
7. Double Inverted Slopes (Part 3676) Size: 2 studs wide, 2 studs deep, 2/3 brick high Characteristic: Multiple sloped sides Use: Symmetrical substructures or as an aesthetic element
What are Inverted Slopes used for?
Aesthetics & Finishes Inverted slopes provide a neat finish to the underside of a structure. Think of vehicles, aircraft or buildings that are also viewed from below. Functional Design They can also contribute structurally to the strength of a structure. The angled shape allows for better distribution of forces in certain construction techniques. Symmetry When building complex MOCs such as mecha-robots, spaceships or futuristic buildings, inverted slopes are often used to create symmetry. Optical effects By combining standard and inverted slopes, you can create unique geometric shapes and optical illusions in your model.
