How To Draw a Brick?

Here are the steps.

Step 1 – Sketch the Brick as a Simple 3D Box

Start by drawing a long rectangle for the top face of the brick, slightly angled so it shows perspective.
From the corners of that top face, draw short connecting lines downward to begin forming the side faces.
Close the shape by drawing the bottom edges, creating a full rectangular prism (box).
Keep the lines very light and straight, using quick sketch strokes rather than heavy outlines.
Make sure the far edges are slightly shorter than the near edges to create depth and a believable 3D angle.
Add tiny corner marks or guide ticks (like in the reference) if it helps you keep corners aligned.
Don’t add shading or texture yet—this step is only about getting the brick’s proportions and perspective correct.

Trace over the main edges of the box with slightly darker lines, keeping corners crisp and clean.
Identify the three visible planes: top face, front/side face, and end face.
Begin shading the side face with light, vertical pencil strokes to separate it from the top plane.
Add a faint shadow tone on the end face as well, slightly darker than the side if it’s turned farther from the light.
Keep the top face mostly light, with only minimal shading near edges to show a subtle surface angle.
Lightly suggest a ground shadow behind or beside the brick, but keep it very soft at this stage.
Maintain consistent perspective by checking that all parallel edges stay aligned in direction.

Start adding small pits, speckles, and tiny marks across the brick faces to suggest a rough material.
Lightly break up the clean edges by adding subtle unevenness—bricks are rarely perfectly sharp in real life.
Strengthen the shading on the side face with more layered strokes, keeping the texture visible through the shading.
Add gentle tonal variation on the top face: slightly darker near one edge, lighter near the highlight area.
Scatter a few texture marks on the side and end faces, but keep them irregular so it doesn’t look like a pattern.
Refine the cast shadow line on the ground, lightly extending it behind the brick to show it sitting on a surface.
At this stage, the brick should look solid and textured, but not yet fully contrasted or finished.

Darken the deepest shadows along the bottom edges where the brick meets the ground to make it feel heavier and grounded.
Increase shading on the side and end faces, using denser cross-hatching or layered strokes for stronger depth.
Add slightly darker tone under the top edge to show a subtle overhang and thickness.
Enhance surface texture by emphasizing a few pits and rough marks, especially in shadowed areas where they stand out more.
Clean up and sharpen the silhouette, making sure the brick’s outline is clear without being overly thick everywhere.
Strengthen the cast shadow behind/under the brick, darkest closest to the brick and fading as it stretches outward.
Finish by balancing the tones: the top face remains the lightest, the side face mid-tone, and the far end face the darkest (depending on your chosen light direction), creating a convincing 3D brick.
