Talon is Giant's cross-country hardtail and it runs XS to XL. Only XS ships on 27.5-inch wheels; every size from S up is 29-inch. Giant publishes rider height on the product page's sizing bar and no rider inseam for any adult bike.
Talon 4 size finder
Height gives you one size, or two when the published height ranges overlap. Stack, reach, and standover settle the overlap.
Enter your height and the Talon 4 size that covers it is marked in the tables below.
How to measureHeight gives the starting size. Standover and reach confirm it.
Height ranges
Height ranges for every Talon 4 size, 151 to 197 cm overall. XS: 155 to 166 cm. S: 163 to 172 cm. M: 169 to 179 cm. L: 176 to 186 cm. XL: 183 to 193 cm.
Size chart
Rider height is Giant's published Talon sizing bar. Giant publishes no rider inseam on any adult bike, so the table shows height only.
XS
5'1"–5'5"
155–166 cm
Smallest Talon frame and the only one on 27.5-inch wheels, with the lowest standover at 684 mm.
S
5'4"–5'8"
163–172 cm
Largest stack step in the ladder, 49 mm over XS, and the first 29-inch size.
M
5'7"–5'10"
169–179 cm
Most riders start here. Stack and reach above are for this size.
L
5'9"–6'1"
176–186 cm
Standover does not move from M: both are 709 mm, so only the cockpit changes.
XL
6'0"–6'4"
183–193 cm
Tallest Talon frame, with 1 mm more standover than M and L.
Start with height. If two sizes overlap, use cycling inseam to choose.How to measure

If two sizes both fit, compare reach and standover rather than assuming the larger size is more comfortable.

Enter your height and inseam for a Giant mountain bike, then compare the result with this Talon 4 chart.
Sizing notes
Riders with the same height can need different sizes because inseam, torso length, flexibility, and preferred handling differ.
3 checks
Talon standover is almost flat from M up: 709 mm at M, 709 mm at L and 710 mm at XL. Reach and wheel size decide the size rather than clearance.
Reach grows 91 mm across the ladder while stack grows 91 mm, so the cockpit and the front end move together. That is unusual for a mountain frame, where reach usually climbs faster.
XS is the only 27.5-inch size. The step from XS to S adds 49 mm of stack and 30 mm of reach and swaps the wheel size, so it is the largest single change in the table.

Questions
Short answers for Giant Talon 4 sizing.
Start with Giant's height band: XS for 155–166 cm, S for 163–172 cm, M for 169–179 cm, L for 176–186 cm, and XL for 183–193 cm. Then confirm standover for the size you land on.
No. XS ships on 27.5-inch wheels and every size from S up is 29-inch. XS also carries the lowest standover at 684 mm against 715 mm at S.
175 cm sits inside Giant's M band of 169–179 cm and inside the L band of 176–186 cm. M carries 606 mm of stack and 436 mm of reach; L adds 19 mm of stack and 20 mm of reach with no change in standover.
Giant publishes Talon M for riders from 169–179 cm (5'7"–5'10"). It carries 606 mm of stack, 436 mm of reach, and 709 mm of standover.
No. Giant builds the Talon from XS to XL, and its sizing bar stops at 183–193 cm. A rider taller than 193 cm is outside the published range rather than between two sizes.
