Custom product sizes with My Templates

Why this is needed

My Templates is a NINEMAGS feature that allows you to create a custom print template based on the real physical parameters of your magnet and your printing requirements.

This feature is useful when standard NINEMAGS templates do not fit your needs, for example if you have:

  • a non-standard magnet size;
  • different requirements for bleed / wrap (additional area for wrapping or bleed);
  • different cut line requirements (cut or alignment lines);
  • different spacing between images on the print sheet (space).

In simple terms, you measure your magnet and printing parameters and create a template “for yourself” so that print sheets are generated correctly and match your production.


Who this is for (and who it is not for)


✅ My Templates is right for you if:

  • you produce magnets in non-standard sizes or use your own dimensions;
  • you need custom bleed, cut lines, or spacing;
  • you want full control over print template parameters.

❌ You do NOT need My Templates if:

  • your magnet sizes and printing requirements fully match standard NINEMAGS templates;
  • you are not confident in your measurements and do not want to risk the final result — in this case, using standard templates is recommended.

Important before you start


  1. All dimensions must be entered in inches.
  2. The SKU must be unique:
  • unique within your account (you cannot reuse a SKU from another template you created);
  • unique across existing NINEMAGS SKUs (for example, if 2x2  is already used, the system will not allow you to save it).
  1. Templates cannot be deleted.
  • A template can only be set to Inactive. This is intentional, to avoid breaking print sheets, stacks, and products where the template has already been used.

How to create a new custom template

Step 1. Open My Templates

  1. In the Shopify admin, go to Apps → NINEMAGS.
  2. Open the My Templates section (from the left-hand menu).

Step 2. Click Add Template

  1. Click Add Template (top right).

  2. The template creation modal will open.

Step 3. Fill in the main fields

3.1 Display Name

This is a human-readable name for your template.

Examples: My 2.5x2.5 template  or Square 2.5 Custom .

3.2 SKU (required and must be unique)

The SKU is a unique identifier for the template.

It is used internally during file generation and in file names.

Example format shown in the hint: ...{sku}...

SKU recommendations:

  • Use clear and unique values, for example:

    2x2_mycustom , 2_5x2_5_vendorA , sq25_custom

  • If you want a SKU similar to an existing one (for example 2x2 ), add a suffix:

    2x2_mynew , 2x2_custom_v2

Step 4. Select the shape (Image Shape)

Choose the magnet shape (for example, square or circle — depending on the available options).

Step 5. Set the final visible magnet size

Fields:

  • Magnet Width
  • Magnet Height

This is the final visible size of the finished magnet, without wrap or bleed.

Example: if your magnet size is 2.5 × 2.5 inches:

  • Width = 2.5
  • Height = 2.5

Step 6. Set the Bleeding Area (wrap / extra area)

Fields:

  • Bleeding Area horizontal
  • Bleeding Area vertical

This is the additional area added around the edges for wrap or bleed.

It increases the final print size (usually by 2× the value, as it is added on both sides).

If you do not need an extra area, set the values to 0 .

Step 7. Set Cut Lines (alignment / cut guides)

Fields:

  • Cut lines horizontal
  • Cut lines vertical

This is the distance from the image edge to the cut or alignment guide lines.

If you have specific requirements (for example 0.1 ), enter them here.

If not, use the default values.

Step 8. Set Space (distance between images on the print sheet)

Fields:

  • Space horizontally
  • Space vertically

This defines the spacing between images on the print sheet during generation.

Examples:

  • 0  — images can be placed directly next to each other (if allowed).
  • 0.1  — adds a small gap, which is often safer for cutting.

Step 9. Click Create

  1. Review all fields.
  2. Click Create.

The template will appear in the My Templates list.

Managing templates in My Templates

After a template is created, it appears in the My Templates list.

Each template has a status and a set of available actions.

Template status

Each template has a Status:

  • Active

    The template is available for selection when configuring a product.

  • Inactive

    The template is hidden from product settings and cannot be selected for new products.

Templates cannot be deleted. Using Deactivate instead prevents breaking existing products, print sheets, and stacks that already use the template.


Available actions

Click the three dots (⋯) next to a template to open the actions menu.

Preview

Use Preview to generate and review print sheets based on this template.

Preview allows you to:

  • verify the final magnet size;
  • check bleed / wrap, cut lines, and spacing;
  • confirm that images are placed correctly on the print sheet.

This step is strongly recommended before using the template in a product.


Edit

Use Edit to modify the template settings.

You can update:

  • Display Name;
  • magnet size and shape;
  • bleeding area;
  • cut lines;
  • spacing between images.

Editing a template affects how print sheets are generated when this template is used.



Deactivate

Use Deactivate to make a template inactive.

When a template is deactivated:

  • it is no longer shown in the template selector inside product settings;
  • it cannot be selected for new products;
  • existing products that already use this template are not broken.

This is the safe way to stop using a template without removing it from the system.


How to use a custom template in a product

After creating and activating a custom template, you can apply it to an existing NINEMAGS product (or specific product variants).

Templates are selected inside the NINEMAGS app and are assigned on the variant level.


Step 1. Open the NINEMAGS product

In your Shopify admin, open Apps → NINEMAGS.

Go to Products.

Click Select Product and choose the product you want to configure.


Step 2. Select the product variant and click Edit

In Manage Product Settings, select the variant you want to edit

(you can select one or multiple variants).

Click Edit.

Templates are assigned on the variant level, not globally to the entire product.

Step 3. Select your custom template

In the Edit properties modal, find the field Button Shape & Size.

Open the dropdown.

Select your custom template (for example: My Template).

⚠️ Important:

Only templates with Active status appear in this list.

If you don’t see your template, check that it is not deactivated in My Templates.


Step 4. Configure the remaining product settings

While you are in the Edit properties modal, adjust other settings if needed:

  • Upload amount — number of images the customer must upload;
  • Paper size;
  • Bulk mode (if applicable);
  • Custom margins (if enabled).

Make sure these settings match your production workflow.


Step 5. Save and verify

Click Save.

Use Preview (if available) to verify:

  • magnet size;
  • image grid and spacing;
  • overall layout on the print sheet.

If everything looks correct, the product is now fully configured to use your custom template.
