These skills will help you communicate your digital models clearly and professionally, making your work stand out in the real world of digital design.
Presentation formats are the forms in which finished interior design visuals, such as renders, animations, drawings and material samples, are put together and shown to clients and other audiences. They include printed boards, digital slide decks, PDF portfolios and booklets, video presentations, interactive panoramas and virtual reality, physical models with sample boards, and web or social media galleries. Each format suits different audiences, venues, budgets and stages of a project, and the right choice makes the design easy to understand and memorable. Example: for the redesign of a regional bank's flagship branch, the designer prepares a slide deck with renders for the board meeting, two printed A1 boards for display in the head office foyer, a material sample board for the finishes discussion and a short PDF booklet for directors who could not attend.
Each format has its own strengths and limitations. Designers often combine two or three formats so that each part of the design is shown in the most effective way. Example: a designer for a beach resort's new villas uses printed boards at the site meeting, where screens are impractical, and an interactive panorama link for the overseas owners.
| Format | Description | Strengths | Limitations |
|---|---|---|---|
| Printed presentation boards | Mounted large-format sheets with renders, plans and notes | Visible all at once, no equipment needed, good for exhibitions | Costly to print and change, bulky to transport |
| Digital slide deck | Sequence of slides shown on a screen | Easy to edit, tells a step-by-step story, can include video | Needs a screen and power, viewers see one slide at a time |
| PDF portfolio or booklet | Multi-page document for reading on screen or printing | Easy to share and keep, good for detailed information | Less impact than a live presentation |
| Video presentation | Edited animation with titles and narration | Shows movement and flow, engaging | Takes time to produce, harder to change |
| Interactive panorama or web viewer | 360° views or 3D models viewed online | Clients explore at their own pace | Needs internet and compatible devices |
| Virtual reality experience | Immersive full-scale walkthrough in a headset | Strongest sense of space and scale | Requires headsets and setup time |
| Physical model and sample board | Scale model and real material samples | Tangible, shows real colours and textures | Expensive and time-consuming to make |
| Web and social media gallery | Online images and short clips | Reaches wide audiences, good for marketing | Not suited to confidential or detailed design approval |
Printed boards remain common for formal presentations, exhibitions and display in client offices. They are planned as a set with a consistent layout so viewers can read them in order. Example: a designer for a county museum's exhibition hall prepares three A1 landscape boards: concept, layout and visuals, displayed side by side on easels.
| Size | Dimensions (mm) | Typical use |
|---|---|---|
| A0 | 841 × 1,189 | Large exhibition and competition boards |
| A1 | 594 × 841 | Standard client presentation boards |
| A2 | 420 × 594 | Smaller boards and sample boards |
| A3 | 297 × 420 | Handout sheets and booklets |
Digital formats are flexible, easy to update and easy to share. They suit meetings with screens and remote audiences. Example: a design studio presenting to an international NGO's regional office runs a slide deck over a video call and sends the PDF version afterwards.
Number of slides = presentation time ÷ average time per slide
A 30-minute presentation, with 10 minutes kept for questions, allows about 1.5 minutes per slide.
Time for slides = 30 − 10 = 20 minutes
Number of slides = 20 ÷ 1.5 ≈ 13 slides
The best format depends on who will see the presentation, where and why. Considering these factors early avoids last-minute problems. Example: a designer presenting a rural health centre's design to a community committee chooses printed boards and a physical model because the venue has no reliable power for screens.
Total cost = number of boards × (printing + mounting) + delivery
Four A1 boards cost Ksh 1,500 each to print and Ksh 900 each to mount, plus Ksh 1,000 delivery. A digital deck needs only a projector hire of Ksh 3,500.
Board cost = 4 × (1,500 + 900) + 1,000
Board cost = 4 × 2,400 + 1,000 = 9,600 + 1,000 = Ksh 10,600
Digital deck cost = Ksh 3,500
The digital deck saves Ksh 7,100, while boards remain on display after the meeting.
