Choose a pet ID tag by its dimensions, thickness, and how it hangs on your pet’s collar. Check the space under their chin and how comfortably the tag hangs.
This guide compares three specific Em & Me Studio designs. Sizes vary within each collection, so always check the product you plan to order.
Tiny, standard, and large tag examples
Tiny tag example
Tiny Tomb
0.81 × 1 × 0.125 in
Width × height × thickness
A compact design with a short name on the front and contact details on the back. Check the fit on your own pet.
Standard tag example
Lucy Heart
1.4 × 1.2 × 0.125 in
Width × height × thickness
A standard heart-shaped tag with a name on the front and contact details on the back.
Large tag example
Clifford Lucy Heart
2 × 2 × 0.25 in
Width × height × thickness
The larger heart design uses thicker acrylic and includes a heavy-duty flat split ring.
Dimensions come from each product description. Measurements exclude the split ring and seasonal mini. Product photos are displayed at the same card size and are not to scale.
| Design | Width × height × thickness |
|---|---|
| Tiny Tomb | 0.81 × 1 × 0.125 in |
| Lucy Heart | 1.4 × 1.2 × 0.125 in |
| Clifford Lucy Heart | 2 × 2 × 0.25 in |
How to check the fit before ordering
The Tiny Tomb is described for cats and dogs weighing 10 pounds or less. The Clifford Lucy Heart is a larger, thicker design. Neither description replaces checking the fit on your individual pet.
- Measure a tag you already like. Note its width and height, then compare it with the product measurements above.
- Make a paper outline. Trace the width and height on paper or print the comparison below. Hold it near the collar while your pet is supervised. Paper is a visual reference, not a wearable tag.
- Allow for the ring and mini. The hanging setup extends beyond the tag itself. Check the whole drop from the collar.
- Check clearance and comfort. Consider the space under the chin and whether the tag could reach a bowl, be chewed, or catch on something.
- Check engraving space. A small tag has less room for text. Use our engraving guide to plan the name and contact details.

Pet tag size questions
What size pet tag should I choose?
Compare the tag’s width, height, thickness, and hanging setup with your pet’s collar and the space under their chin. Start with a tag they already wear comfortably if you have one.
Are all Tiny Tags the same size?
No. Shapes and dimensions vary. The Tiny Tomb measurements in this guide apply to that design only.
Is a large tag always better for a large dog?
No. A larger design may suit your preference, but check its position, thickness, and how it hangs. Choose a size your pet can wear comfortably.
Can a cat wear a standard tag?
Fit depends on the individual cat, collar setup, and design. Compare the dimensions and clearance rather than choosing by the product photo alone.
Are these photos actual size?
No. Product photos are resized for the page. Use the listed measurements or the printed outlines after checking the calibration line.
Does a mini change the overall size?
Yes. A mini and split ring add to the complete hanging setup. The listed tag dimensions do not include those accessories.
