House from the corner
A 9 × 11 m two-storey house at 35 mm from the corner, with a figure for scale.

What to look at
The two facades recede to opposite vanishing points; the corner is the nearest vertical and the tallest.
Eye level at 1.6 m crosses the ground floor: doors and the figure's head all meet the horizon.
The house is 6.5 m tall, about four figures; check it against the person.
What this scene is for
A 9 × 11 m two-storey house at 35 mm from the corner, with a door and a figure for scale. The scene for suburban exteriors, property illustration, and the most common two-point exercise in every perspective course.
The mistake it settles
Making the house too tall for its footprint. At 6.5 m it is roughly four figures high, and the figure in the scene is there to check it. Buildings drawn without a scale reference come out either dolls' house or tower block, and neither is what you meant.
The camera
| Lens | 35 mm on full frame |
| Camera height | 1.6 m above the floor (standing) |
| Rotation | 40° to the scene's axes |
| Tilt | level (verticals stay vertical) |
| Objects | 9 × 11 × 6.5 m block · 2.1 m door · 1.75 m figure |
| Floor | 1 m squares |
Measured off this render
Taken from the same camera model the tool draws with, on the 1340 × 754 PNG above.
| Angle of view | 54.4° across (35 mm on full frame) |
| Horizon | 437 px from the top, 58% of the image height |
| Depth-axis vanishing point | 423 px beyond the left edge |
| Width-axis vanishing point | 883 px beyond the right edge |
| Object | Distance | Height on the render | Below the horizon |
|---|---|---|---|
| 2.1 m door | 14.3 m | 195 px | 76% |
| 1.75 m figure | 15.8 m | 152 px | 91% |
| 9 × 11 × 6.5 m block | 24 m | 353 px | 25% |
Draw it from these numbers
- Rule the horizon across the sheet at 58% of the picture height — 437 px down on this 754 px render. Every other line in the scene is measured from it.
- Two vanishing points on that line: 423 px beyond the left edge, and 883 px beyond the right edge — close enough to reach on a larger sheet.
- Set the scale from the 2.1 m door at 14.3 m: 195 px tall, with 76% of it below the horizon. That share is the camera height divided by the object's height (1.6 ÷ 2.1 m), and it is the same for every object of that height anywhere in the picture.
Open the reference in the tool to move the camera, change the lens, or add your own objects at real sizes; the share link keeps your version. Draw over the PNG at 30–50% opacity in any app with layers.
Question
How do I check a building's height without measuring anything?
Use a person. A standing adult is about 1.75 m, so a two-storey house is roughly four of them stacked, and a door is 1.2 of them. In this reference the door, the figure and the roof line all read against the same horizon, which is what makes the check possible at any distance.
