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.

Stimolantè Black Classic Strut Mounts

Traditional Finish for Professional Photo Presentation

Timeless Professional Presentation

Stimolantè Black Classic Strut Mounts are designed for photographers who value a timeless, traditional presentation style. Precision cut from 1240gsm black recycled board and finished with a bold black foil border framing the entire aperture, these mounts deliver contrast, structure, and visual weight to the finished print.

Rooted in long-established British photographic presentation standards, the Classic range is trusted by professionals working across schools, studios, events, and institutional photography, where consistency and presentation quality matter.

Key Specifications:

  • 1240gsm Board Weight
  • 100% Recycled Black Board
  • Precision-Cut Apertures
  • Bold Black Foil Border
  • Integrated Strut Stand
  • Through-Dyed Construction

Designed for Professional Presentation

The Classic Black mount is engineered not only to protect your print, but to elevate it. The wider, foil-blocked border guides attention straight to the image, creating a structured, formal presentation that complements both colour and monochrome photography.

Key Features

1240gsm Board Thickness

Rigid, durable construction for professional handling and long-term display. The substantial weight ensures mounts maintain their structure through client handling, packaging, and display without warping or bending.

100% Recycled Black Board

Dyed through the core for a rich, consistent finish with a reduced environmental footprint. The through-dyed construction ensures the black colour extends throughout the board rather than just surface coating, maintaining appearance even at cut edges.

Bold Black Foil Border

A traditional, high-contrast frame that suits formal presentation styles. The foil-blocked border creates visual separation between mount and image, directing viewer attention whilst adding premium tactile quality that clients notice and appreciate.

Precision-Cut Apertures

Clean edges and accurate cutting help prints sit neatly and consistently. Professional-grade cutting ensures apertures align precisely with print dimensions, enabling rapid assembly whilst maintaining the clean presentation expected in professional photography deliverables.

Ideal For

School & Nursery Photography

Professional package presentation with a classic, formal border that photographs well and displays cleanly. The traditional black mount aesthetic meets parental expectations for school photography whilst the rigid construction withstands the handling requirements of high-volume school deliveries.

Studio & Portrait Photography

A timeless finish for family portraits, legacy prints, and formal studio packages. The black foil border adds gravitas to portrait presentations, particularly for generational photography and formal family sessions where traditional aesthetics align with client expectations.

Graduations, Proms & Ceremonies

Ideal where presentation quality needs to match the importance of the occasion. The formal black border reinforces the significance of milestone events, providing a presentation style that complements the ceremonial nature of graduations and formal celebrations.

Equestrian, Pet & Newborn Work

A strong, premium-feel mount for keepsake-style images that clients often display at home. The substantial board weight and traditional aesthetic create deliverables that feel valuable and worth displaying, encouraging prominent placement in client homes.

Corporate & Institutional Photography

Smart, consistent presentation for formal portraits, awards, and organisational photography. The professional black mount aesthetic aligns with corporate environments and institutional standards, providing presentation that commands respect in business settings.

Black-and-White & Heritage Styles

The black border adds contrast and structure, complementing monochrome and classic aesthetics. For photographers specialising in black-and-white work or vintage-inspired photography, the black foil border enhances the timeless quality whilst providing visual separation that makes monochrome prints stand out.

Whilst these are common applications, Stimolantè strut mounts are used by photographers across the UK wherever presentation quality influences perceived value.

Frequently Asked Questions

  • What is the actual outer dimension of each mount size? +

    The sizes listed (4×6", 5×7", etc.) refer to the photo insert aperture, not the outer mount dimensions. The outer dimensions are larger to accommodate the black foil border and provide structural stability. For precise external measurements needed for packaging or shipping calculations, please refer to our comprehensive Size Chart or contact us on 0208 527 6006 for specific dimensional information for your required sizes.

  • How does the black foil border differ from printed borders? +

    Foil blocking is a premium finishing technique that applies metallic foil under heat and pressure, creating a raised, tactile border with superior durability and visual quality compared to printed borders. The foil-blocked border resists wear from handling and maintains its appearance indefinitely, whilst the tactile quality adds perceived value that clients notice when handling mounted prints. This traditional finishing method is preferred in professional photography for its longevity and premium feel.

  • Can I use these mounts for both portrait and landscape orientations? +

    Yes, the strut stand mechanism supports both portrait and landscape orientations, providing flexibility for diverse photography compositions. The aperture shape determines the primary orientation (portrait apertures for vertical photos, landscape apertures for horizontal), but the strut adjusts to maintain stable display regardless of orientation. For mixed orientation deliveries, simply ensure you order the appropriate aperture configuration for each print format.

  • How do I insert prints into the mounts? +

    Prints slide into the mount from the side, securing behind the aperture for a clean, professional finish. The rigid 1240gsm construction maintains its shape during insertion, whilst the precision-cut aperture ensures prints align correctly without excessive force. For high-volume assembly, the consistent sizing and clean-cut apertures enable rapid mounting without sacrificing presentation quality, making them efficient for busy photography businesses.

  • Why choose black mounts over white or cream options? +

    Black mounts provide high contrast that creates visual separation between mount and image, making colours appear more vibrant and details more defined. This high-contrast presentation suits formal occasions, traditional aesthetics, and black-and-white photography particularly well. The bold black border creates a framing effect that directs attention inward to the photograph, whilst the classic black aesthetic aligns with traditional presentation standards expected in school photography, formal portraits, and ceremonial events. Many photographers maintain both black and lighter mount options to suit different photography styles and client preferences.

  • Can I purchase mixed sizes in a single order? +

    Yes, you can order multiple sizes to accommodate diverse print formats within your photography business. Many photographers stock several sizes to serve different client packages and event types—for instance, 4×6" for standard school portraits, 5×7" for family packages, and 8×10" for premium deliverables. Ordering multiple sizes ensures you maintain appropriate inventory for varied photography applications without requiring separate orders for each format.

  • Are volume discounts available for high-volume users? +

    Yes, we offer volume pricing for photographers and labs with significant mount requirements. School photographers, high-volume portrait studios, and print labs often benefit from bulk ordering that reduces per-unit costs whilst ensuring consistent inventory during peak seasons. Contact our sales team on 0208 527 6006 to discuss your volume needs and receive customised pricing that reflects your regular usage patterns across the sizes you require.
