schwalbe marathon real world widths?

I’m about to swap my conti touring tires for some Schwalbe Marathons.

The rims are magic open pros (new profile)

The contis are 32 but measure 33mm on the rims.

Do I get the Marathons in 35 (hoping they will be the normal 2mm smaller)

Or do I get the 32 Marathons and hope they are at least 32 on my rims.

I don’t have a ton of space due to mudguards.

In my experience Marathons come up to the stated size.

Marathon Supremes size small, my front 35mm is ~33mm and the rear 40mm is ~37mm on my Marasa hybrid.

I expect the 32mm in the spares box would easily fit my Attain GTC road bike.

i find em a bit odd sizing.

got some 42c on my tourer, which are smaller than the pair of 40c i have as spares.

The 35c Marathons on my tourer (37-622 or 28×1.4) measure up 35 to 36mm on 19mm internal width rims. HTH.

Thanks hmmmm…. I might gble on the 35 and hope it inflates to 33ish.

I got 35c and its close on frame.  Road surfaces are awful on my daily ride I would like more clearance.  Sorry I can’t measure actual width I am away.
