Acrylic Ratio Calculator
Calculate optimal liquid monomer to powder polymer ratio for acrylic nail applications, plus product usage estimates.
About this calculator
This calculator separates two questions acrylic techs ask daily: whether the bead on your brush matches your intended wetness, and how long current inventory will last. Your Liquid-to-Powder Ratio converts powder grams to volume at zero point eight milliliters per gram, then divides liquid milliliters by that volume (lines 19-21). Ideal Ratio for Bead Size is independent of what you poured -- it equals zero point nine plus bead size times zero point thirty-five, giving about 1.25 for small dry beads, 1.6 for medium, and 1.95 for large wet beads (line 25). Ratio Quality Score measures how far actual drifts from ideal: one minus the absolute gap divided by ideal, scaled to a hundred-point scale and floored at zero (lines 50-52).
Per-set usage estimates come from bead-size tables -- liquid per nail rises by zero point one milliliters per bead step while powder per nail falls by zero point zero five grams (lines 29-30) -- multiplied by Nails per Set (lines 34-35). Sets per Day scales those into daily and monthly totals using twenty-two working days (lines 37-42). Sets from Current Stock divides available liquid and powder by per-set needs, floors each, and takes the smaller number so neither component runs out first (lines 45-47). Bead Size and Sets per Day never enter the ratio comparison itself; they drive ideal targets and inventory math instead.

How to Use This Calculator
- Enter the amount of liquid monomer (mL) you have on hand.
- Enter the amount of acrylic powder polymer (g) available.
- Select your bead size preference: 1 = small/dry, 2 = medium, 3 = large/wet.
- Set nails per set (typically 10) and your average sets per day.
- Review your actual liquid:powder ratio vs. the ideal ratio for your bead size and your ratio quality score.
- Use the monthly liquid (mL) and powder (g) usage estimates to plan supply orders.
How the result changes with Powder polymer (g)

|---|---|
| 5 | 3.75 |
| 7.5 | 2.5 |
| 15 | 1.25 |
| 25 | 0.75 |

Frequently Asked Questions
Why does Bead Size change Ideal Ratio but not Your Liquid-to-Powder Ratio?
Your ratio is computed only from the liquid milliliters and powder grams you enter, converting powder to volume at zero point eight milliliters per gram before dividing (lines 19-21). Ideal Ratio comes from a separate bead-size formula -- zero point nine plus bead size times zero point thirty-five (line 25) -- and Ratio Quality Score compares the two (lines 50-52). Bead preference sets the target wetness; what you actually mixed sets the measured ratio.
How does the calculator decide how many full sets my current stock can do?
It first estimates liquid and powder needed per set from bead size and nails per set (lines 29-35), then divides your on-hand liquid and powder by those per-set amounts, floors each result, and reports whichever limit is lower (lines 45-47). That minimum prevents overstating capacity when one component would run out before the other.
Do Sets per Day affect how good my mix ratio is?
No. Ratio Quality Score depends only on the gap between actual and ideal ratios (lines 50-52), and actual ratio uses just liquid and powder on hand (lines 19-21). Sets per Day feeds daily and monthly usage projections (lines 37-42) but never enters the ratio comparison or quality score.
Why does a drier bead preference use more powder per nail in the usage estimates?
Per-nail powder is calculated as zero point three five minus bead size times zero point zero five grams (line 30), so small dry beads at size one allocate more powder while large wet beads at size three allocate less. Liquid per nail moves the opposite direction -- zero point two plus bead size times zero point one milliliters (line 29) -- reflecting that wetter mixes pull more monomer per nail.
