Using the Dent Estimator
Counting dents takes skill to learn and I guess must be mastered over time. But what about the size and depth? Generally, dents that area larger or deeper take longer to repair. PDR estimators quoting vehicles must therefore calculate the number of dents categorised according to size and depth.
Using the Dent Estimator
A tool already exists to assist in estimating dents based on size known as the dent estimator. It consists of holes of specific diameters. Any dents that fit these sizes are then classified according to size and are priced in accordance with insurance companies.
In Australia dent sizes are grouped according to generally 3 or 4 sizes considered for PDR quotations – Size 1 to Size 4 largest. Coins can be used also to categorise dents according to size.
| Size 1 | Size 2 | Size 3 | Size 4 |
| 5 cent coin | 10 cent coin | 20 cent coin | 50 cent coin |
International Standards for dent size differ slightly and are slightly larger than our coins in the table
# 2 = 28mm diameter
# 3 = 36mm diameter
# 4 = 48mm diameter
Using the Dent Estimator, sizes can easily be observed as well as the Dent Density estimated.
Dent Estimators are available for purchase but you can easily make your own tool using holes of the sizes provided below.
1. Mark each hole towards the bottom of a white sheet of paper (laminate later) or plastic white sheet based on the diameters provided.
2. Cut out each hole accordingly. Remember to leave sufficient space and border area for the large hole.
3. Cut the larger hole away from the other holes. The diameter of the large hole is 15cm (6 inches).
4. Laminate both sides if you used paper.
Diameters to be used for the holes of size 1 to size 4
# 2 = 28mm diameter
# 3 = 36mm diameter
# 4 = 48mm diameter
This too, can work quite well as a measure of dent density and hence dent count.
