How Many Drills Do I Need?
SECTION 1 - Observation
Most diamond painters eventually encounter the same problem, running out of a colour before the artwork is finished.
​
It rarely happens evenly.
One shade finishes early while others remain unused.
​
This usually occurs:
-
Near gradients
-
In background fill areas
-
In heavily dithered regions
-
After correcting misplaced drills
Even when charts are mathematically correct, real placement behaviour is not perfectly predictable.
Small variations accumulate across thousands of placements.
SECTION 2 - Mechanism
Drill charts calculate quantity based on pixel count.
​
But pixels ≠ drills used.
​
Real usage differs because:
-
Placement pressure varies
-
Some drills are rejected visually
-
Some drills flip or mis-seat
-
Some are replaced during straightening
-
Some colours visually demand correction
Additionally, drill materials have different densities and weights.
Therefore:
1 gram is not a fixed number of drills across materials.
​
Acrylic, resin, crystal, AB, and metallic drills all contain different counts per gram.
Charts are accurate mathematically, but incomplete physically.
SECTION 3 - Studio Method
We treat drill quantities as a tolerance system, not a perfect calculation.
​
For every colour:
We intentionally supply more than the chart requires.
​
This prevents:
-
Dye lot replacement mid-project
-
Colour shift in gradients
-
Visual patching
Our restocker calculations and reference tables are based on actual measured counts rather than theoretical pixel totals.
​
The goal is not minimum supply, the goal is uninterrupted completion.

Drill counts by grams
SECTION 4 - Mechanism
Instead of finishing a canvas with substituted shades or waiting for replacement drills:
​
You finish the artwork using the same colour batch.
​
This produces:
-
Consistent gradients
-
Correct colour balance
-
No patching zones
-
No visible repair areas
The artwork looks finished because it was completed continuously.
SECTION 5 - Practical Takeaway
-
Drill charts are a guide, not an exact usage value
-
Different drill materials contain different counts per gram
-
Gradients consume more drills than flat colours
-
Corrections and straightening increase usage slightly
-
Extra drills prevent colour mismatch repairs
STUDIO NOTE - CONTEXT & LIMITATIONS
The DMC palette remains the foundation of diamond painting and is essential for universal replacement and availability.
​
We intentionally include additional drills per colour in our kits.
​
Not because charts are inaccurate, but because real crafting behaviour differs from mathematical models.
​
The aim is continuity, not minimal packing weight.
​
The reference tables below exist so you can plan confidently when ordering additional drills especially across different materials.
​
It fills the visual gaps between existing colours so artwork can retain depth while remaining fully compatible with the standard system.
​
This reference explains why two patterns of the same image can look fundamentally different despite using the same material format.
