silly handle bar question

ok so was just hoping to get some help with the handle bar size on my bike.
The only markings i could see on the was HB 3035 and something like 490 mm which i’m assuming is the width. Would any know one what size the circumference for the stem is?
I know there are very similar diameters 25.4, 26mm etc and I don’t have any measuring tape on hand.

Any help would be appreciated, thanks!

these? probz 25.4

Hey Kiasu,
they look very similar…i guess i will just take the risk and order some 25.4 bars. :smiley: thanks for your help mate.
