A bit smaller.

Touch 4G: 102 x 62 x 11

iPhone: 115 x 61 x 12

The Samsung Z Flip is probably your best bet if small size is the most important factor - though, er, slightly more expensive than the HMD!

Z Flip 7: 86 x 75 x 13

Thanks so that's like the same ballpark, which kind of validates my counterpoint about "small" phones (which at the time were considered immense)

Flip phone is cheating! Haha kidding. Still a Z Flip 7 is giant when unfolded.
