How to use/select new floorboards to fit with Old floarboard

[Whimsical]

Not sure if I am using the best fitting boards but I'm hoping someone might advise how would I get a good match between old and new. Floor boards where taken up here and there by a number of tradesman and damaged. Obviously looking to make good myself.

Actual measurements of existing floorboards are 140mm by 23mm (approx)
The actual measurements of the closest boards I could find are 136mm by 21mm (150mm x 25mm from Jewsons).

While the difference might seem small it is not ideal. I can gap the new boards slightly to make up for the width but I'm assuming that this is a common problem. If so, what would you advise I do to address the difference in thickness. I was only planning on putting thin carpet down and in time I would expect the 2-3mm difference to become apparent. I was thinking of getting some 2mm glazing shims from somewhere and fixing them to the floor joists?

Could anyone advise please on how a professional would do this?

Many thanks

What percentage of the floor is being replaced? odd boards or big sections?

Hello,

Odd boards mostly (quite a lot Some wer'nt great to begin with) but a couple of sections (i.e. 3 or 4 adjoining each other).

I'd use reclaims if I were you. I hate so see new in with old.

Local timber merchant should stock a closer size match.

Couple of thoughts:

If the replaced boards will be visible, move some original ones from an area of the room where the boatds won't ever be seen (eg under a sofa), and put the new ones in there.

Local timber merchants will have a thicknesser machine and if you offer them the price of a pint or two I'm sure they'd run a few boards through it for you to get the exact thickness you want.
