Fuji Grand Tour tire tubes
I have a FUJI Grand tour and the tire size stated on the tires say 27x1 1/4, but when I purchased 27x1 1/4 road tire, it looks really big! What kind of tire tube do I need?

27 1/4 can indeed look big. Just go to your lbs, buy a tube that's suitable, and fit them. If you THEN find the tyres are a bit fat, just appreciate the extra comfort and buy skinnier when they wear out.

Are we talking about a tire or a tube? Assuming that you are replacing a tube rather than the tire: Yes, those tubes look too big for the tire, but they do fit. The tube should be marked 27 x 1 1/4. If it is, it will fit. If you are replacing the tire, I'm surprised that it doesn't look the same as the old one, but if it is marked correctly it will fit.

Don't mistake the folded/boxed condition of a tube with it's inflated condition. Ever gone shopping for pants? One holds the pants against their body with the pants waist placed at your waist. then you note that the pant's cuffs are touching the ground. But when those same pants are tried on the cuffs don't touch the ground any more. Tubes are the same. Flattened into a ribbon, to roll up (as in a box or seat bag), the tube will have a greater circumference the when it has some air in it and it takes a 3 dimensional shape. This is one of the reasons that we partially inflate a tube before installing it.
Then there's the whole issue of labeled sizes not being actual measurements and that a labeled tire (and tube) from one company might not have the same actual dimensions compared to another company's similarly labeled tire. Again think back to clothing. Company A might call their 29" inseamed pants 29" but company B's 29" inseam might be a bit different in actual fit. Andy

I went through that with my wife's 1970s Schwinn. The old (original?) 27"x1-1/4" tires were not more than 1-1/8" wide and the new Paselas are bang on 1-1/4"/32mm, and look much bigger. (And ride much better!)

You need a 700c 28-32 mm tube.
Something like this: https://www.niagaracycle.com/categor...28g-27-x-1-1-4
Your new tires may look bigger than the old ones because they have knobs, etc.
Check the Panaracer Pasela PT tire, it's slick.

maybe you wish for a 27 x 1 1/8" or 27 by 1".. they should all say 630.. on the sidewall ,(& 28 or 25mm)
the international standard for bead seat diameter of a 27" tire. (in metric equivalencies )
