Shrink measurements accurately for models, prints, and planning. Choose factor, percentage, or ratio based scaling. Review results fast with charts, exports, and practical guidance.
| Original Width | Original Height | Original Depth | Mode | Scale Input | Scaled Width | Scaled Height | Scaled Depth |
|---|---|---|---|---|---|---|---|
| 240 mm | 160 mm | 40 mm | Direct factor | 0.25 | 60 mm | 40 mm | 10 mm |
| 120 cm | 90 cm | 15 cm | Percentage reduction | 35% | 78 cm | 58.5 cm | 9.75 cm |
| 48 in | 36 in | 12 in | Ratio scaling | 1:3 | 16 in | 12 in | 4 in |
1) Linear scaling multiplier:
Multiplier m = factor, or m = 1 − p/100, or m = numerator / denominator.
2) Scaled length:
Scaled dimension = Original dimension × m.
3) Scaled perimeter or diagonal:
Any one-dimensional measure scales by m.
4) Scaled area:
Scaled area = Original area × m².
5) Scaled volume:
Scaled volume = Original volume × m³.
6) Reduction percentages:
Linear reduction = (1 − m) × 100
Area reduction = (1 − m²) × 100
Volume reduction = (1 − m³) × 100
7) Estimated cost:
Scaled cost = Original cost × mᵏ, where k is 1 for linear, 2 for area, and 3 for volume based estimation.
Scale down means reducing every dimension by the same multiplier. The shape stays proportional, but width, height, depth, area, and volume all become smaller.
Use factor mode when you already know the exact multiplier, such as 0.5, 0.25, or 0.8. It is the fastest option for direct resizing.
Percentage reduction tells the calculator how much to remove. A 25% reduction keeps 75% of the original size, so the multiplier becomes 0.75.
Enter numerator 1 and denominator 4. The calculator converts that to a multiplier of 0.25, meaning each dimension becomes one quarter of the original.
Area depends on two dimensions, so it follows the square of the multiplier. Volume depends on three dimensions, so it follows the cube of the multiplier.
Yes. The calculator automatically derives area from width and height. It derives volume when width, height, and depth are all available.
It estimates how cost changes with size. Linear suits one-dimensional materials, area suits surfaces, and volume suits solid objects or material-heavy parts.
Yes. It works well for drafting, model making, packaging mockups, print planning, prototypes, educational examples, and proportional design adjustments.
