Window is 33 1/2 inch what size blind do I need

The actual width of the Trim+Go faux woods blinds is 1/2 inch smaller than the listed width. That is to allow for the installation brackets on each end. The 33 inch blind would be a good fit for a 33 inch window opening but may be too small for your window opening as it would actually measure 32 1/2 inches. Having the next size up cut to your width would allow for a better fit. - Kimberly
