Dimensional weight on shipping rates

[AndrewG123]

My store sells products that are heavy and are packaged in large boxes. Because of this shipping rates just based on weight won't be accurate on shopify. So is there a way a can input dimensional weights in shopify so that the shipping rate is accurate? Can I put the dim weight in the weight section of each product or do I need an app to do this.

@AndrewG123 hope you are well,
If you're familiar with coding or using custom metafields, you can store the dimensions of the products in metafields and use an app or custom Shopify script to calculate dimensional weight based on those values. 

I hope it works for you, let me know, and If you'd like to discuss this more, don't hesitate to send me a PM

Thank you
