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.
