Photo Mount Size Guide

Photo Mount Size Guide

When selecting a mount for your photographs or prints, it is important to understand two key measurements: the insert size and the outer mount size.

Mounts are typically named according to the photo size they hold, rather than their external dimensions.

1 Insert Size

The insert refers to the photograph or print that sits behind the mount aperture. The print should be slightly larger than the aperture opening so it remains securely positioned behind the mount.

Example: A mount designed for a 4×6" photograph will usually have an aperture slightly smaller than 4×6".

2 Mount (Outer) Dimensions

The outer dimensions describe the full size of the mount itself. These measurements are important when choosing suitable packaging or frames.

Packaging: Bags or envelopes should always be slightly larger than the mount's outer dimensions.
Framing: The frame opening should be large enough to accommodate the mount comfortably.

Branded Contemporary Black Strut Mounts (Packs of 100)

Add a professional finish to your Contemporary Black Strut Mounts with custom foil branding. Choose from silver, black or clear foil (pillow emboss) and a range of branding positions — from bold and visible to discreet and subtle. Whether you're showcasing portraits at events or packaging prints for clients, branded mounts help reinforce your name with every photo delivered.

We offer four branding positions to suit different styles, layouts and customer preferences. Each foil application is precision-stamped for a crisp, professional look.

  • L-Shape Branding – Our most popular style, applied along the bottom edge for visibility in both portrait and landscape formats.
  • 45-Degree Branding – A clean diagonal foil mark in the bottom-right corner, ideal for subtle branding.
  • Horizontal Branding – Foil applied underneath the aperture, typically centred or offset depending on your layout.
  • Back Branding – Keep the front minimal while displaying your logo or contact details discreetly on the back.

Choose from three standard foil colours:

  • Silver: high contrast – our most popular choice.
  • Black: subtle tone-on-tone branding for a sleek, understated look.
  • Gold Foil: warm, premium finish – ideal for wedding or seasonal branding.
  • Clear/Pillow Emboss: for a more minimalist, modern, embossed look

Pricing & Setup

  • £5 per box: Branding is just £5 per box and is automatically added at checkout for orders below 10 boxes.
  • Free branding on 10+ boxes: Order 10 boxes (1,000 mounts) or more and enjoy free single block and location branding.
