Gluten free flours weight

Can anyone tell me the gluten free bread flour and gluten free all purpose flour weight per cup. Having problems with flour measurements. And want to try weighting it to see if it helps. Thanks

150g per 1 cup of Breadtopia GF bread and all purpose flours

(300g = 2 cups here)

(38g = 1/4 cup here)

Thanks I will try weighting it and see how that works.
