How can I add product dimensions for each item on my ecommerce site?

Topic summary

Users are seeking a way to add individual product dimensions (length, width, height) to items in Shopify, beyond just weight. This is critical for businesses selling varied-sized products like home appliances, where weight alone doesn’t determine shipping costs.

Core Problem:

  • Shopify currently lacks native support for assigning specific box dimensions to individual products
  • Only default packaging settings exist, treating all products uniformly
  • This leads to inaccurate shipping rates, potentially causing lost sales or revenue

Proposed Solutions:

  • One participant suggests using third-party delivery management tools (e.g., InstaDispatch) that support per-product dimensions and weights
  • These integrations can provide more precise shipping calculations and improve checkout conversion rates

Status: The discussion remains open with no official Shopify response. Participants are calling for native dimension support as a basic feature to improve shipping accuracy across all stores.

Hi there,

I was just wondering if you know or have a way to add product dimensions to each individual product on shopify?

We sell home appliances which come in many shapes, sizes and weights. However the weight of a product doesn’t necessarily account for the size of the product. Sometimes the heaviest items can be smaller than the bigger items. We are trying to give customers the best and most accurate shipping rate when it comes to this as we feel we are losing sales and/or money due to incorrect shipping rates when a customer leaves the checkout or purchases the product with the incorrect shipping rate.

Could you please help with this?

Thank you.

Similar boat to you. We need to be able to somehow assign a specific box size to a specific product. Different products are different sizes for us and we’re not being efficient with shipping costs because there is only a default option for all products. I think shopify reckons we only are 1 product shops on here. It’s a ridiculous situation to be in. Surely this is a basic need, to allocate packaging to a product and not just have a default 1 size fits all method.

Hey MrPaul_McCaw,

Thanks for your response and I completely agree! Hopefully Shopify allows the the input of product box product dimensions in the near future as this will really generate an accurate shipping rate for customers, thus helping businesses that are in the same boat as us! Should we have access to this, I feel sales across the board of all businesses will greatly increase, which in turn will generate more income for Shopify!!

P.S. Please take note Shopify!

I’ve faced a similar issue before, and adding product dimensions is crucial for accurate shipping rates. While Shopify doesn’t natively support assigning box sizes to individual products, third-party tools can help.

For instance, delivery management solutions like InstaDispatch allow you to include dimensions and weights for each product, ensuring more precise shipping rates. It’s helped me reduce shipping cost errors and improve checkout conversions.

Hope this helps!
