Product Details Beyond Size

Some product types do not need a traditional size chart. These notes help buyers understand what to check before selecting wall art, mugs, stickers, tote bags, or phone cases.

Posters & Wall Art

Posters and canvas-style wall art are best for artwork-heavy designs, dorm rooms, studios, offices, bedrooms, and collector displays. Paper type, frame depth, and exact print size may vary by selected product and fulfillment partner.

Mugs

Mugs work well for quote graphics, funny designs, office desks, coffee corners, and gift-ready artwork. Capacity and finish may vary by selected mug option.

Stickers

Stickers are best for small collectible graphics, laptops, notebooks, water bottles, lockers, and casual gift add-ons. Surface, finish, and size may vary by product option.

Tote Bags

Tote bags are useful for everyday errands, books, market runs, and casual carry. Graphic placement and bag material may vary by product style.

Phone Cases

Phone cases are device-specific. Availability can vary by iPhone or Samsung model. Choose the correct device before checkout; case material and finish may vary by product option.

How to Measure & Care

Flat Garment Measurement

  • Lay a similar garment flat on a table.
  • Width: measure from armpit to armpit, one side only.
  • Length: measure from the highest shoulder point to the bottom hem.
  • Sleeve: measure from shoulder seam to cuff when listed.
  • Double the width for approximate full chest circumference.

Care Tips

  • Wash apparel inside out with cold water.
  • Use mild detergent and similar colors.
  • Avoid bleach and harsh chemicals.
  • Air dry when possible or tumble dry low.
  • Do not iron directly on the printed design.

Product & Size Guide FAQs

Should I choose my usual size?

For most unisex T-shirts, yes. Choose one size up if you prefer a relaxed, oversized, or layered fit.

Why do different products fit differently?

Different apparel styles use different cuts, fabric blends, and production batches. A hoodie, women’s tee, tank top, and youth shirt will not fit exactly the same.

Do wall art, mugs, and stickers need a size chart?

Not like apparel. For those products, check print size, capacity, finish, device compatibility, or product details before checkout.

Can measurements vary slightly?

Yes. Small measurement differences are normal because items are produced and measured in batches. Allow about ±0.8 inch / ±2 cm.
