My Bag
Your clubs, your numbers, kept in your own browser — and a check on the gaps between them, measured against what the makers actually publish.
Pick your iron set and the lofts fill themselves in from the manufacturer's own published specifications. Add your wedges and woods, and the bag checks the gaps between every club you carry. Everything stays on this device. There is no account and nothing is uploaded: no club, loft or length ever leaves your browser. The only thing our analytics records is that the tool was used, how many clubs were counted and whether any gaps were flagged — three numbers, never the clubs themselves. Your bag lives in local storage and one button wipes it.
Step OneStart from a published set
Choose the irons you play and the lofts and lengths load from the maker's own spec table. If your set is not here, skip to step two and type the numbers in — they are usually on the maker's product page, and on many sets the loft is stamped on the sole.
Specifications are read from each maker's own published pages and checked August 2026. Loading a set replaces the clubs currently in your bag.
Step TwoYour clubs
Tap a club to add it. It arrives on a sensible number and you nudge from there — no typing unless you want to. The starting figure is not an invented standard: for irons it is the median of what the published sets on this site actually list, and for everything else it is a figure a maker publishes. Each club tells you where its number came from and how wide the real range is.
Step ThreeWhat your bag says
Add at least two clubs with lofts to see your gaps.
Gap guidance is measured, not invented: across the nine current iron sets on our loft chart, consecutive lofts step by 2° to 6°. Anything outside that range is wider or tighter than the makers space their own sets. Loft gaps are not distance gaps — the same four degrees opens a bigger yardage gap between long irons than between wedges.
Why botherBecause the label is not a measurement
A club number tells you where a club sits inside its own set and almost nothing else. A Titleist T350 7-iron is 29°; a Titleist 620 MB 7-iron is 35°. Both say 7. That is why this page asks for lofts rather than club names, and why it sorts your bag by loft when it checks the gaps.
The gap that catches most golfers is at the bottom of the set. Modern game-improvement irons finish with a strong pitching wedge — 43° is common — and a traditional 56° sand wedge sits thirteen degrees below it. Nothing on either club warns you, and no chart of standard lofts can tell you, because it depends entirely on which set you own.
These pages carry the published figures this tool is built on, and each has its own checker. They do not yet read your bag — you still enter your numbers separately on each one. Wiring them to this page is the next job, and until it is done we are not going to pretend otherwise.

PrivacyWhere this data lives
In your browser, on this device, and nowhere else. My Bag uses local storage, which is a small amount of space a website is allowed to keep on your own machine. We cannot read it, it is never transmitted, and it does not appear in any analytics we collect — the only thing measurement ever sees is three numbers — how many clubs you counted, how many wide gaps were found and how many tight ones — and never a club, a loft or a length.
That also means the bag is tied to this browser. Open the site on your phone and you will start with an empty bag. Clearing your browser data clears it too. If that matters to you, print the spec sheet and keep the paper.
