Two calculators we built because every gym owner and retailer we work with ends up needing them. No accounts, no email gates, no ads. Use them once or embed them on your own site — credit appreciated but not required.
Boxing Glove Fit Calculator
Find the right glove ounce in 10 seconds
Enter body weight, hand circumference (optional), age group, and intended use (training / sparring / federation-rule competition). The calculator returns the recommended size, factors in hand wraps, and applies World Boxing / IFMA / WAKO competition rules where relevant.
- Adult, junior, and child fittings
- Metric & imperial units
- Federation-rule modes (World Boxing, Pro, Muay Thai, kickboxing)
- Outputs a Quote-CTA pre-filled with your size

Wholesale ROI Calculator
Model landed cost and margin before you order
Enter your supplier quote, freight, duty, target retail, and expected sell-through. The calculator outputs landed cost per piece, gross margin, break-even units, payback time, and a margin-quality verdict. Multi-currency (USD/EUR/GBP/AUD/CAD).
- 8 inputs, 8 outputs
- Margin-quality verdict (loss / tight / healthy / premium)
- Pre-fills the Quote form with your quantity tier
- Useful for comparing two supplier quotes side-by-side

How these calculators came about
The Glove Fit Calculator started as a paper laminate stuck to the wall of a gym in Manchester that orders from us. It mapped body weight to glove ounce, then added a hand-circumference column when the owner kept fitting smaller-handed members in oversized 16 oz training gloves. We digitised it and made it available to every buyer.
The Wholesale ROI Calculator started as a spreadsheet template we used to send to first-time buyers asking “is 250 pieces worth it?” The answer always involved the same eight inputs. Eventually the spreadsheet became this web tool.
Both are open-source in the sense that the methodology is documented on each tool’s page. Use them as-is, fork them, or build your own — the underlying tables and formulas aren’t trade secrets.
Embed either calculator on your site
Free to embed — useful if you run a gym, fight-gear blog, or e-commerce shop and want to give your audience a fit-check or margin-check tool.

- Container Loading Calculator — work out how many pieces fit in a 20′ or 40′ container based on carton dimensions, plus volumetric weight for air freight.
- Custom-Print Cost Modeller — for OEM buyers comparing embroidery vs sublimation vs debossing across order sizes.
If you have a tool you wish existed, email us — we build the ones our buyers actually ask for.
