Discover the subtle intricacies involved in architectural documentation, specifically the disparity and significance of scale in detail drawings. Learn how details can be presented at different scales to effectively communicate essential information about the structure.
Key Insights
- The article emphasizes the importance of scale in architectural details, noting that they often zoom in on smaller areas and are presented at different sizes to better illustrate key information.
- It highlights the concept of scaling in architectural drawings, where a specified measurement on the plan represents a larger, real-world measurement. For instance, an inch and a half on a drawing could equate to a foot in reality, depending on the chosen scale.
- The article also stresses the importance of clear labeling and referencing in architectural details to ensure clarity and understanding for the contractor and their team.

You will realize that most of these details are on a different scale than the one we have been working on before. Most of the documentation work that we have been seeing so far has been dealing with a quarter of an inch equal to a foot, an eighth of an inch of a foot, and three sixteenths of an inch equal to a foot. These details are enlarged, they are zooming in on smaller areas.
So, this scale here says that an inch and a half is equivalent to a foot. Let's go back a second. When we are dealing with the plan of the plant and if a plan of the plant is a quarter of an inch equal to a foot, which means that a quarter of an inch printed represents a foot in the real world.
That this scale of an inch and a half is equivalent to a foot, is equivalent to saying an inch and a half is equal to 12 inches. We multiply by cross and we get an eighth. So this image, this detail is an eighth of the full size.

Again, the information of the real world, the beams of 2x4, the glazing and that information is presented to an eighth of the real size. While here, for this typical door header, you can see that the scale says three inches is equivalent to a foot. Three inches is equivalent to a foot.
It is the same as saying that three inches represent 12 inches, which means that an inch represents four inches. So this image is a quarter of the real size. And if you look at objects like the head that is happening here, and the condition of the head that is happening here, and the scale is considered.
You can see that this three-inch drawing is equivalent to a foot is twice as large as this one-and-a-half-inch drawing is equivalent to a foot. So, again, in a sheet of details, we do not always have the same scale represented. We will often have enlarged images documented throughout the building presented in a sheet detail.
The images are referenced in the same planes. Again, when you were in the floor plans and in the elevations, you saw the references in those documents to these details. These details are presented at different scales, different sizes, to better communicate the important information.
If, for example, I zoom in on this area, you can see that in this condition, once again I have an inch and a half equal to a foot of detail. And if I move down here, you can see that I am having similar types of information simply presented on different scales. So this is the first of our detail pages.
What I would like to do is draw your attention to this condition here. You can see that this detail says no to scale. It is very common, especially in structural plans, to see details that are drawn not to scale.
If you look at the detail page, you will notice that the text has a constant size throughout the drawing. It is the factorization scale of the details that is different. One thing that is also very important in a detail is to make sure that when you are labeling something, you are pointing to the element you are labeling.
We do not like to have leaders or arrows floating in space. But we have arrows pointing to the element that is being documented. You can see that in this drawing, we are also showing that the interior of the building is here, the exterior of the building is here.
Again, our goal is to make the information as clear as possible for the contractor and his team.
