Warm-up ladder, IWF plate colors, and an inventory-aware plate calculator." url: https://platescalculator.com/120-kg --- 1. [Home](https://platescalculator.com) 2. 120 kg # How to load 120 kg on a barbell Per side (20 kg bar) 2 × 25 Per side: 2 times 25 kg 120 kg is a strong intermediate milestone and one of the cleanest loads on the bar: two 25 kg red plates per side on a 20 kg bar, nothing else. Same plate both times means fast loading and an instantly readable stack. If you only own one pair of 25s, inventory mode rebuilds the second 25 a side from 20s and 15s. 120 kg is the tidiest same-plate load in the red zone, two 25s a side and done, which is why it strips and reloads so fast between sets. In pounds it is about 265 lb, sitting between the 250 and 275 marks, a hair over halfway from two to three plates. ![A lifter gripping a loaded Olympic barbell](https://platescalculator.com/_astro/barbell-hold-victor-freitas.DkDKRFYg_1tQmjO.webp) Photo: [Victor Freitas](https://www.pexels.com/photo/703012/) / Pexels ## Warm-up ladder 1. 20 kg 2.

The Home Screen version above already covers most of it. But if enough lifters want a real App Store / Play Store app, I'll build one. Leave your email and tell me honestly whether it'd be worth a few dollars to you – that's what decides it. ## How barbell plate math works Barbell math is simple arithmetic that's surprisingly easy to get wrong under fatigue. Take your target weight, subtract the bar (20 kg or 45 lb for a standard Olympic bar, 15 kg or 35 lb for a women's bar), then split what's left evenly between the two ends. Whatever plates you load on the left must be mirrored exactly on the right. That's all a plate racking calculator does – instantly, without the mid-session mental math. Some lifters call it plate math, others barbell math; either way, a good barbell loader does it in one tap, so you know the bar is loaded right before you get under it. 🏋️ If you think in gym shorthand, my ["how many plates" chart](https://platescalculator.com/how-many-plates) translates one to seven plates a side into real numbers. Competition kg plates follow the IWF color standard – 25 kg red, 20 kg blue, 15 kg yellow, 10 kg green – so an experienced eye reads the load by color alone. Load biggest-plate-innermost so the sleeve seats cleanly and the bar stays balanced. The math is the same whether you run calibrated competition discs or a mixed bag of iron. Where most calculators fall down is assuming you own a perfect plate set. Real garage gyms are a patchwork of hand-me-down and second-hand plates. Plates Calc solves your target against the plates you actually own, uses fractional micro-plates for exact small jumps, and shows the closest achievable weight when an exact load is impossible. It works as a gym calculator for any lift: each milestone page doubles as a warm-up calculator with a ready-made ramp up to your top set, and the whole thing runs as an offline barbell loader you can add to your phone's Home Screen – no sign-up, no connection needed. ### FAQ How does a barbell plate calculator work? It subtracts the bar weight from your target, halves the remainder for one side of the bar, then finds the plates that add up to that per-side weight, mirrored on both ends. Does it work with a limited or mismatched plate set? Yes. Tell it how many pairs of each plate you own and it solves your target using only those plates, and shows the closest weight you can actually load when the exact number isn't possible. Does it support fractional or micro plates? Yes. It handles fractional plates down to 0.25 kg or 0.25 lb, so you can hit exact targets like 62.5 kg for small progressions. Does it work offline? Yes. Add Plates Calc to your Home Screen and it opens and calculates with no connection at all – basement gyms included. How much weight is 'two plates' or 'three plates'? In US gyms a 'plate' means one 45 lb plate per side of a 45 lb bar: two plates = 225 lb, three = 315 lb, four = 405 lb. Counting 20 kg plates on a 20 kg bar: two plates = 100 kg, three = 140 kg, four = 180 kg. ## About ![Marina, the maker of Plates Calc](https://platescalculator.com/_astro/marina.CwyhBOp2_Zqww7S.webp) Hi, I'm [Marina](https://visionandcode.substack.com/) 👋 As a tech-girlie I genuinely love creating (wellness) products that solve real problems – and loading a barbell with a mismatched set of plates shouldn't take mental arithmetic mid-session.
