Dynamic Sheet - Free Size

This feature allows your customers to input custom dimensions (height & width) for their DTF sheets. It calculates prices dynamically based on the exact area.

Unlike preset sizes, the Dynamic Sheet Free Size option gives customers complete flexibility. And if you allow that product for DesignLab, then a product image will be generated for the entered size.

How to set the Dynamic Sheet Free Size

Step 1: Access to Product Options


Hover over Products from the InkyBay app’s top menu and select Product Options as the image shown below. 

Step 2: Navigate to your product option set

Click + Add New Option Set to create the new option size and assign to the product.



Step 3: Option set name & apply rule to option

Insert the option set name(e.g., Choose product as a bundle) and then set the Apply Rule value to any of these Type/Vendor/Tag/Handle. 



Step 4: Create a Custom Free size option

 Click the Select Option Type to select the Custom Size – Free Size option. And then click the + New option button.

Step 5: Set the option title and enable for designlab

Set the option title, then you can enable or disable it for the designlab.

If you enable the custom free size option for designlab you will get a white blank canvas according to the custom size or preset size that the customer selects on the product page.

Also, you can change the selected custom size/preset size inside the designlab. Blank canvas size will be changed according to the selected size.


Otherwise, click the Disable button if you do not want to show the custom free size option on designlab. By disabling, you will be able to see the original product image that you have uploaded in the Product setup for the design tool (advanced settings). Custom size/preset size option will be shown only on the product page.

Step 6: Size Units Display Settings 

It will help your customer to choose their preferred Size Unit on the product page. You can set up the Size Unit Display settings as Multiple Choice in the admin panel. 


  • Inch: This will help your customer to choose the Size Unit as Inch

  • Centimeter: This will help your customer to choose the Size Unit as centimeters

  • Feet:  This will help your customer to choose the Size Unit as feet

🎯Note

The size units will be displayed in the Custom Size option in a dropdown. Your customer can choose one of the size units from the front end.

Incremental Factor: You can allow your customer to increase/decrease the value in an incremental factor. For this:

  • Set it to a round value or a floating point value. 

  • Select the incremental value in inches, centimeters, or Feet units. 

🎯Important

If you turn the option to “Yes”, then the value will be incremented according to the assigned incremental factor.  

If you turn the option to “NO”, then the incremental value restriction will not work.


Step 7: Minimum/Maximum Size and base unit for calculation

 If you want, you can set the Minimum & maximum measurements for the width and height of the product in three different calculation units (Inches, Centimetres, and Feet).


Below, we’ve discussed in detail. 

  • Calculation Unit: This allows you to show your customers on which scale the values of the height & width are set to the custom size box.


  • Width & Height Label: You will see two input fields: Width label & Height label to assign values. Share a clear indication to your customer to set the proper values for sizes. 


  • Minimum & Maximum values:  You can set the minimum & maximum values for the width & height. It helps the customers to choose sizes of any value within your preferred range. [Note: Customers can’t exceed the restriction that you’ll set.]  


Step 8: Custom Size Pricing 

You can set a per square inch price. Your assigned price will be calculated according to the entered custom size. 


Step 9: Size Display Settings 

For preset size display, as you’ve noticed, there are three options: Radio, Swatch, and Select to display the Preset Sizes. If you don’t want to display, simply click the Hide button.

For custom size, insert your custom size Title and select Enable if you want to allow customers to enter their custom size for height and width on the product page.


If you do not want to show the custom size option on the product page, you can disable the option by clicking on the disable button.

Step 10: Preset size

To show two or more size values, click on the + New size button and then enter the title, width & height values, and price. 

After completing all steps, save the option.
