Tube size
I am working on a bike that takes a 26 by 1.5-inch tire and inner tube. In the course of changing the tires, I pinch flatted the tube. Of course, I don't have that size inner tube. I will try to patch it but my success rate with patches is non-existant. I am wondering if I can substitute a similar size. If nothing else I will order one. I just would like to get this off my to-do list. Any ideas. Thanks.

Did you try Googling 26 X 1.50" tube?

Go down to your local shop and they should be able to get you a tube if not you can find 26 tubes pretty easily. Always get the right size tube for your bike unless it is an absolute emergency and there are no other options (like maybe on tour in the middle of Mongolia and you need to get going asap and cannot wait for DHL)

Also, fool proof patch repairs:
1. Locate hole in tube and remove or fix whatever in tire or rim caused the flat
2. Lightly scuff the area around the holes in the tube with sandpaper or the little scuffing tool included with patch kit. Scuff an area slightly larger than the patch you are putting on.
3. Put a healthy glob of the cement on the tube near the hole and spread it thin with your finger so the glued area is larger than the patch.
4. WAIT!!!! for the glue to dry. Usually around 2-5 minutes. It should be not tacky or just barely tacky if you touch the edge of the glued area with your finger.
5. Remove foil from patch, but leave the clear cellophane on the other side
6. Press exposed orange side of patch on to tube, covering hole. Press it on good and hard with the corner of the box the patch kit came in. Work from the centre towards the outer edge of the patch.
7. Reinstall the tube and inflate. Do not bother trying to inflate the tube before it is mounted inside the tire as it might cause the patch to start peeling up as the tube stretches.
On second thought, I should add a step before all that:
0. Get a patch kit with separate patches and a tube of cement. Do not use the 'glueless' or 'instant' patches as they are crap.

Thank you for all the advice.
It is a 1.5. Also discovered the leak is in the valve stem on the original tube. Tried a new core but still leaking.
I ended up using a 1.75 tube. Nicked that putting it in though. Urrr. But that's how I discovered flex seal tape makes a decent patch. I didn't have any patches. Been holding almost a week now. Will see how it does after a few rides. That stuff is pretty gluey though; so I think it will hold.

I dont exactly recommend it, but you can get away with the wrong size 26" tube.

Most 26" tubes are for fat tires. 26x1.5 is not very fat so make sure you get a narrower tube if and when you buy a new one. I always have to insist at the bike shop that I need a narrow tube.

I have a 1.75 in there now. 26 inch of course. It seems to be doing well. Have to get it out for a ride and see how it rolls.

I've found that tubes labeled 26 x 1.1 - 1.4 work for 26" tires from 1.25 to 1.6.
