To read a furniture drawing, match the views, read the dimensions and then explain each design choice by linking it to a need. A drawing answer earns marks when it gives a reason, not only a description.
This lesson belongs to the wider SPM subjects and learning resources section. The drawing below is original and described in words.
How do the views fit together?
Every view shows two of the three sizes. The front view gives width and height, the side view gives depth and height, and the plan gives width and depth.
The height in the front view and the side view must agree. If they do not, one of them has been misread.
Worked example: a small study table
An original drawing shows a study table. The front view gives an overall width of 1 200 mm and an overall height of 750 mm. The side view gives a depth of 600 mm. The top is 25 mm thick, and the legs are 50 mm square.
Leg length. The legs run from the floor to the underside of the top: 750 − 25 = 725 mm.
Check. Leg plus top thickness: 725 + 25 = 750 mm, which matches the overall height.
Top area. 1 200 × 600 = 720 000 mm², which is 0.72 m² because 1 m² is 1 000 000 mm².
Justifying a joint or material choice
Suppose the drawing labels a rail joined to each leg and the question asks why the rails sit just below the top. A justification could read: “Rails placed just below the top tie the legs together and stop them from racking sideways, so the table stays rigid when someone leans on it.”
For a material, link the property to the use. A hardwood top resists dents from daily writing, while a lighter board might reduce cost and weight. State what you gain and what you give up.
The mistake that loses marks
A weak answer says: “The table has four legs and two rails and a top, and it is made of wood.” That describes the drawing and justifies nothing.
The stronger answer picks one feature, says why it is there and says what would happen without it. A feature with no stated purpose is only a description.
Checking against a need
Good justification starts from a stated need. A student table needs a surface big enough for books, a height that suits sitting, and strength for daily use.
Write the need first, then link each feature to it. This keeps the answer focused and makes it easier for a marker to give credit.
Check yourself
A second original drawing shows a bookshelf with an overall height of 1 800 mm, four shelves of 18 mm thickness and a top 18 mm thick, with five equal gaps, one under each board (the lowest gap is between the floor and the first shelf). Find the total thickness of the four shelves and top, then the height of each gap.
Answer
Five boards of 18 mm make 5 × 18 = 90 mm. The remaining height is 1 800 − 90 = 1 710 mm, shared by the five gaps.
With five equal gaps, each gap is 1 710 ÷ 5 = 342 mm. Check: 5 × 342 = 1 710, and 1 710 + 90 = 1 800 mm, so the parts fill the height.
What to study next
Test your justifications with the structured-answer self-review tool. A similar reason-for-every-feature habit is used in explaining material and form choices for an original craft concept.
