Hello,
We can provide those measures in the pleated fabric perfect fit blinds,
please find link below to these options-https://www.blindsbypost.co.uk/perfect-fit-blinds/perfect-fit-pleated-blinds
But we cannot in the wood and metal venetian blinds as the small size affected the controls the blinds due to being too small a width unfortunately as need more room due to having the tilt and lift controls,
my apologies for this.
