Free bowling tools and guides at a glance
This page collects the free bowling tools and guides on the BOWLIO website: a bowling shoe size chart, a simple system for picking up spares, explanations of scoring, rules and oil patterns, and a demand calculator for bowling centers planning a rental shoe fleet. Everything is free to use and needs no account.
Bowling shoe size chart
Bowling shoe sizes are given in different systems depending on the country and the brand. Our bowling shoe size guide explains how to measure your feet and how US, EU, UK and Japanese sizes relate to each other, and it shows how to check the fit of a new pair.
Picking up spares
A converted spare scores ten pins plus the next ball, an open frame scores only the pins knocked down. Three guides help you practice spares systematically:
- The 3-6-9 spare system – keep your target and adjust where you stand, so one reference line covers many spare leaves.
- Spare shooting angles – which angle to use for corner pins and common multi-pin leaves.
- Picking up the 10 pin – a step-by-step method for the corner pin, with the mirrored 7-pin version for left-handers.
Rules, scoring and lane conditions
- Bowling rules explained – fouls, pinfall and what counts.
- How bowling scoring works – strikes, spares and the tenth frame, step by step.
- Oil patterns for beginners – why the ball reacts differently from lane to lane.
- Bowling glossary – common terms from A to Z.
Rental shoe calculator for bowling centers
If you run a bowling center, the demand calculator on our page for bowling centers gives you a first estimate for a rental shoe fleet. You enter the number of lanes and choose the type of venue, and the calculator suggests a total number of pairs and a spread across sizes. The figures are planning estimates; you can send the result directly as an enquiry and agree the final spread with us.
Your own bowling shoes
Once you know your size, you can choose your own pair. BOWLIO bowling shoes are made of genuine leather, upper and sole, with a slide sole under both shoes, so they suit left- and right-handed bowlers. Sizes are listed in EU, US and JP, with women's sizes. Why owning your shoes makes a difference is explained in why your own bowling shoes make a difference.
