Who This Is For
- - Powerlifters and strength athletes training in kg gyms.
- - Home-gym users with constrained or mixed plate inventories.
- - Coaches who need fast, repeatable setup instructions across lifters.
Kilo Plate Calculator
KG-first plate setup built for real gym speed. Use basic mode for fast in-session loading or pro mode for exact constrained inventory solving, profiles, and transitions.

When Not to Use This Tool
- - Do not assume machine base weights are universal across brands.
- - Do not skip collars on work sets when using closest-over fallback.
- - Do not ignore visible plate damage or mislabeled equipment.
Worked Examples
Competition setup (exact)
Target 190.00 kg, Olympic bar 20 kg, collars 2 kg, calibrated inventory available.
Result: Exact result with per-side loading and mirrored lb output.
Home gym constrained inventory (fallback)
Target 137.5 kg with limited 1.25 and 2.5 plates.
Result: Nearest under and nearest over candidates shown with safe default recommendation.
Method Summary
This page uses an exact bounded solver for custom inventory, with objective-aware candidate selection and nearest under/over fallback outputs when exact loading is impossible.
Assumptions
- - Bar/base and collar weights are entered correctly.
- - Plate counts represent total available plates (both sides).
- - Result selection follows training context (safety vs overload intent).
Safety
- - Default to nearest-under fallback for high-intensity sets.
- - Load and verify sleeves symmetrically before unracking.
- - If technique degrades, reduce load regardless of calculated target.

FAQ
Calibrated vs standard plates: does it matter for this tool?
Yes. If your gym uses non-calibrated plates, use custom per-plate counts and trust the nearest fallback guidance for practical setup.
How do machine base weights work here?
Select the machine preset, set its base weight in kg, and the solver treats it like the starting system weight before plate loading.
Why does the tool show nearest under and nearest over?
When exact loading is impossible with your inventory, both options are shown so you can pick safely and intentionally for the session goal.
Which fallback should I choose for heavy work?
Default to nearest under for safety unless your programming explicitly requires over-target loading.
Why keep a lb mirror output in a kg-first tool?
It prevents communication mistakes when athletes and coaches mix unit systems.
Can I save multiple gym setups?
Yes. Pro mode supports local profile save/switch, plus export and import JSON.
