The Math Class The size shown on the door is 15" wide x 48" tall. If you would like this to be HORIZONTAL instead of vertical, please put that in the Personalization field. The icons will be turned to accommodate. Please measure your door to determine the correct size for you. Most classroom doors are approximately 36" wide to allow wheelchairs to enter easily. Color shown is Black. I use the best vinyl available, Oracal 631, for this design. It is rated for 3 years outdoors & lasts indoors for 10+ years. Vinyl lettering looks like it was professionally painted. It has a matte finish & is easy to apply. It is also easy to remove without damage to walls & other surfaces. However, it cannot be repositioned or re-used. It adheres best to clean, dry, smooth surfaces: painted walls, glass, metal, doors, cabinet doors, plastic, sanded wood, tile, cell phones, laptops, car windows, etc. Small color samples are available on request. Each order comes with small vinyl samples (so you can practice) & an applicator card. For perfect placement most orders have several “+” signs across the top which are center & level marks. For orders with multiple colors, triangles are placed in the design for perfect alignment as shown in the last picture for those listings.
