One inch give or take.

Sears carries a number of measuring calipers that could greatly assist with measuring your chain adjuster. They range in price from around $7 for the pocket job or over a $100 for a pro digital model with metric dial ones that fall somewhere in between. Have a look at Sears.com and search under "calipers"  Of course there is also the laserline method between the front and rear wheel axels OR a string plumb if you don't have the laser.

Use the Wheel Alignment method below for reference.

Here's a cool alignment device for the Harley boys. Anyone feel like jury rigging one of these babies for the TBA/Speedmaster. Interesting read anyway.
ENOUGH! Anyone else?

Frank, Piper is right. 25mm equals 1 inch.

What I have found is that with the chain properly adjusted (on my bike anyway) it will just barely touch the bottom of the swing arm pad. This is right at 25mm. I prefer to run my chain a tad on the loose side as I am AHEM... a bit on the large side. A little loose is FAR better than a little tight.
Also, depending on what kind of chain lube you use, always check and adjust the chain BEFORE you squirt on your favorite slick stuff. Using PJ1 myself, after I adjust the chain I lube it and once the lube has set up, I have only about 7mm of slack on the chain. However after riding for about a mile, say to the local Stop-N-Rob, the chain is back to normal.

Turn both bolts 1 side (1/6 turn) at a time to keep the original alignment.

Count the threads on each adjuster with a toothpick. Or use a calibrated measuring device. Greybeard's suggestion works, if and only if, the adjusters are even to begin with. Make sure the adjusters are seated against the adjuster brackets too.

i have a micrometer but it is tough to fit in a position to measure both sides. i have put about 100 miles since i adjusted it and seems fine. so i am just going to lave it.
